Sounds nice, but I can't afford the $300 for parts for a while.

(and more importantly, I've spent all my "capital" for a while with my wife. Need to let that build back up for a few months. Speaking of which, I should be cleaning up the house right now. Bye-bye :))

We would be interested, but the midwife checked me yesterday and said that things are "starting to happen" so we won't be making any plans for the next few weeeks. After that with a three year old, a one year old and a newborn, we'll have plenty of free time.

i am just too lazy to make flanges. too cheap to buy andy's.
nate,
Whant to loan out your jig for flanges?

NateHanson
11-23-2004, 08:46 PM
I'll loan out anything, but we didn't make flanges for this last project. The tops were glued directly to the body of the skimmer.

I made a 6" kalk reactor with a flange, but I didn't make a fancy jig because there was just one flange to make. I must have an 8" pattern around for the outside (the inside is just pattern shaped to the inside of the tube after they're glued).

I just remembered how I made my flange. I turned it on the lathe. Also turned a retaining channel for the O-ring to sit in.

If people want to make flanges I'll turn you a pattern so you can easily make them with the router.

We have a lot of room to do it, but not much in the way of tools. We have a four car garage (two deep, two wide) and a barn/workshop with electricity (but not heat).

spectrum
11-24-2004, 12:13 PM
I have the tools but not a lot of room. Now that winter is upon us and I really have nothing better to do after everybody here goes to sleep I'll make the same offer I made last year. Contact me and we can set up a time to build one one these in my 100 year old cellar (yes it's dusty and a little cramped) but I think I was able to make about 10 of these last year over the winter (nickoz, Heavydc2, Neo, jackfors, abbottsjumper, mikestod and others all have reactors I either built or assisted in) . I have a design I like to use, but if you have one you want to try out lets give it a shot.
One thing you'll need in addition to the tube (s) is 3/8 or thicker acrylic for the flanges and base. Anything thinner tends to bend and leak.
I think Scubadave should have first dibs because he's been waiting since last year (he's a busy man from the sounds of it)

Happy Thanksgiving.

Spectrum (or whatever your name is),

Although I hate to put this public, you already did so I feel obliged to respond in public.

After ruining my past weekend and your failed attempt to ruin my reputation with other members, I find your offer distasteful, to say the least. I don't want to be held accountable for something you did (or you think you did) for me, like you already tried to do.

If you trade something with someone then whatever you traded is no longer yours OK? The person can do whatever they want with it. If you're not satisfied with what you got in return say something right away. Don't keep if to be used against the person it the future. Just so you know I gave the two tanks for free. I hope you enjoy the frags I gave to you.

I see your game coming here trying to play the nice guy but just FYI, I don't play these games. I am what I am, to everyone, with no discrimination, and I don't know what are your real intentions with this but I just can't deal with someone like you. So if you want to play the game you're going to have to play by yourself, I will no longer read this thread.

And as you can see, you ruined my Calcium Reactor building as well. I guess I'm going to have to shell out $300 to buy a new one, but believe me, it's well worth it.

Take care,
Armando

well back on subject i have found a site that has a JBJ setup Includes two gauges, solenoid, bubble counter, needle valve and check valve. Fixed working pressure-meaning when you open the C02 tank valve, the regulator automatically ajusts it to the correct working pressure. for $99 price is good but not sure if the supplier is and what shipping would be here is the site http://www.aquabotanic.com/abstore/en-us/dept_3.html

well, I am sorry that someone had to lose there temper here (it was really tough), as you can see who it might be. Those of you that are still interested... everyone but... you should at least talk to Dan (spectrum) who actually gave a solemn post. He built mine last year, I think it was his second(only got better from there), and its fantastic. Anyone that has talked to him knows what kind of person he really is, not the portrale that someone else has(look at little deeper). Yes he is a personal friend of mine, yes he does not post too much on the board, but if you talk to anyone who has met him will say the same thing I do. I am not really trying to defend Dan in anyway(there is no need to.. lol), his actions speak more then someone elses words. If you have any questions about how to build a reactor, why not ask. He has made some professional looking skimmers and likes to help out a reefer in need.

I think it is more fun (although probably much less productive) to get together and build a bunch at once. How hard would it be to bring the nessecary tools to one place and get some built in a day, then have beer? Are the nessecary tools truck transportable?

I would like to build my own calcium reactor. I think that its going to be cheaper than buying a already made one, and I think I will save money in the long run by not having to add additive.

I have NO idea how to go about doing this, but I am willing to shell out cash for beer, pizza, supplies, etc.

just say when and where and how much if it has not been established already.

I have access to some tools from my neighbor as well. good stuff. power tools baby.

Here is an example of one of the reactors I've built. I have made a few modifications to the recirculation manifold. Instead of using 1 "+" connector for water and CO2 inlets, I used 2 "T" connectors instead.

As I have stated before, I have no problem helping people make these but I really cannot fit that many people into my cellar workshop.

Dan, thats a real nice reactor. I only see one minor problem

For all of you that want to build reactors and have the tubes from the EBAY purchase I have a little project for you. In order that these tubes mate perfectly to both that base and the flanges the ends HAVE to be made flat. The best way I have found is to take a piece of 300 grit wet/drive sandpaper spray contact adhesive on the back and glue it to a very flat surface. I use a piece of medium density fiberboard.
Now, take your tube into both hands and sand the bottom of the tube using a circular or figure eight motion all the time keeping a firm downward pressure.
This technique is very similar to one used by people who make there own mirrors for telescopes. When one end is done, do the other. Repeat for the second tube. This will take a while but is absolutely nessesary. I would strongly suggest that those who want to build reactors do this, it will save us time when assembly time comes.

MarkO
01-09-2005, 02:36 PM
Spectrum, do you happen to have a link or a supplier for the tubes?

spectrum
01-09-2005, 02:43 PM
Afraid I don't. Mine came from an EBAy group purchase. You can buy 6 in extruded tubes from local plastics companies

spectrum
01-13-2005, 09:52 PM
Here is another item those of you making reactors will need, O-rings.
I've been buying mine from www.allorings.com

For those of you who want to use flanges for the top of the reactor tubes, these are essential. Here is what I use on a flange for a six inch tube

Website: www.allorings.com (they are in Hampton Falls, NH)


2-258 EPDM O-RINGS 70D BLACK

These are 6.00" diameter 1/8 thick silicon O-rings sutible for very harse enviorments, much greater that they will see in a reactor. (Sorry, I'm an engineer and have a tendancy to over-engineer my projects)

You can buy them from either USPlastic.com or mcmaster.com

Another supplier for O-rings of any size or material is Marco Rubber in North Andover. They gave me a few 6 1/4" and 4 1/4" o-rings when I stopped in there a couple months ago. Nice folks, and local too.

Armando
01-14-2005, 11:51 AM

I've got two 4 1/4" x 3/16 o-rings that I don't have immediate plans for. You can have them if they're the right size for you. Marco rubber is also right up here, so you could stop by and get exactly what you need next time you go to aquaaddicts or someone's place up here, if you want a different size.

Armando
01-14-2005, 01:03 PM

Armando's reactor will be like all the recent reactors I've made. 2 6' tubes 18" tall, flanges on both. Pump underneath forcing a CO2 enriched water upwards through a diffusser plate and then media and then recirculated. a smallet tube will connect the first tube to the second to assist in the offgassing of extra CO2 from the water, then exit the top of the second tube.
There are a few pics floating around on BRS about one of my reactors

spectrum
01-27-2005, 08:16 AM
you mean the tubes? very carefully on a table saw. Then I take some 220 grit wet/dry sandpaper and glue it to a piece of mdf. Then take the ends of the tubes and sand in a circular or figure 8 motion until flat, then do it again with 300 or 400 grit paper.

MarkO
01-27-2005, 09:52 AM
Actually, it appears that you cut circular parts from the flat acrylic sheet. By any chance do you have a template, or the dimensions you cut the flat pieces to?

Piscevore
01-27-2005, 11:16 AM
Find a circle shaped something.Make sure its hard. STICK it to your acrylic and use it to pattern route an acrylic disk.

NateHanson
01-27-2005, 12:02 PM
Ryan's advice works if you have something flat and round (i.e. not a dinner plate - you need it to have good large-area surface contact in order to safely stick it to the acrylic). Use double-sided carpet tape, available in the flooring section of HD/Lowes. After sticking the two together use a clamp to press around in various places to make sure you have a secure bond. It could be hazardous to your present 10-fingered-state if the pattern and stock were to separate during routing. After all that, carpet tape is more than sufficient for pattern routing.

A good way to make an initial pattern is to cut an acrylic square a quarter inch larger than the circle you want to make. drill a 3/8" or larger hole through the center of the acrylic square (the hole-center needs to be exactly the pattern radius away from one edge, and slightly farther from the other edges). Get a piece of plywood that you can clamp to the top of your router table. Drill a hole in it a little more than the pattern radius away from where the router bit will be. Push a 1" length of dowel into the hole. Mark where the edge of your circle will be on the board, and run the board into the router bit until you are just up to the line. Do it once more to widen the path for the bit. Turn off the router. Clamp the board in place on the router table. Put your square onto the dowel, turn on the router and turn the workpiece. You'll get a perfect square.

Now if you want different sized circles, just drill another hole in the plywood, and move the dowel to the appropriate radius distance from the router bit.

NateHanson
01-27-2005, 12:06 PM
Or tell me what size pattern you need and I'll turn one on the lathe and bring it to the meeting.

MarkO
01-27-2005, 01:09 PM
Do you have the dimensions that you cut these pieces of the flat acrylic to?

spectrum
01-27-2005, 04:22 PM
I make my flanges exactly how Nate said in the above message. I start with a roughly 8inch blank. I draw line from from all corners to their opposing corner. This gives you a center mark then I take a square and mark from the center mark out to the sides. This will leave you with 8 lines converging on a center point. Drill a 1/8 hole on center and follow Nate's instructions above.

Now at the 1/8 hole on center and use a compass to lay out my bolt hole pattern, about 3 3/4 from the center I swing an arc. everywhere the arc crosses a line is where I drill a hole. It makes it easier to mate the top and bottom part of the flange and drill one hole, tap that hole and insert bolt. Now drill another hole and tap, insert bolt. Now you can drill the other 6 without messing up the hole patter on the two pieces.

MarkO
01-27-2005, 06:16 PM
Thanks Nate and Spectrum for your help. I think I may cut the flanges tomorrow night before I quaff a few pops... but if I am too thirsty, I just may go with square flanges :D

No real reason not to make square flanges, in fact the reactor I made for HeavyDc2 has them. I just make mine circles because I made the router jig to do it, plus I can polish the edges nicely by attaching it to my drill press and hitting the edges with progressively finer sandpaper and then 0000 steel wool. I figure if I'm going to make somebody a reactor, it may as well look quasi-nice. I'm a frustrated yankee craftsman woking in a computer engineers life. And yes, after a couple of pops, I've made a few flamges

Well, I got all the parts to build my reactor. Cut and sanded the tubes. Anyone else gotten started yet?

Got photos of the tube ends? Just curious how they came out. Did you use the methode I mentioned?

MarkO
01-31-2005, 06:44 PM
I used a 60 tooth 10" blade on the table saw. Since I couldn't make the cut in one pass, I just kept rotating the tube. To take off the burrs and blade marks, I rotated the tubes over some 100 grit then 220 grit.
Should I sand them down to 400? (I have Weldon #4)

NateHanson

Dan, can you tell me what the three ports on the vertical PVC are each for? (I'm guessing pH, tank water in, tank water out?)

Also, How does the pump detach from the bottom of the reactor, is there another union? And how do you attach the PVC to the top-side of the tube?

What do you use for screen material on the bottom to keep media away from the pump?

How is the second chamber connected to the first?

Thanks, Nate

spectrum

First off Marco...perfect job. no need to go with 400. I don't used Weldon at all, I use Plextic , it's a very watery solvent applied with a squeeze bottle with a hypo needle on the end.

Nate,
The three connectors starting at the top.
1st This is a CO2 feedback loop, it's attached to the top on the main reactors flange. It helps suck any unused CO2 back into the pump for recirculation.
2. H2O input
3. CO2 input

I mount the pumps as such. I take the impellor housinf off and screw it into the 1/2 NPT hole on the base in the center of the tubes footprint. I the reassemble the pump.
The PVC manifold is attached to the tube via a 1/2 NPT hole. I use a threaded to slip connector with teflon tape.

The screens are just 1/4 inch acrylic sheets that I glue 1/8 grid paper on, the start drilling, about a gazillion holes (I know there must be perforated plastic sheets out there but I'm too lazy to look, and I've never been fond of eggcrate for this application.

The first chamber is attached to the second by 2 John guest fittings and some semi rigid tubing. From the top of the first to the bottom of the second. This connection is made on the backside so it's hard to see in the photos.

MarkO

Dan,
Regarding the top flanges, I'm assuming the lower flanges that are glued to the tubes have a 6" opening (router cut), and an approximate 7.5" or so outer flange? I also assume the top covers do not have any holes (with the exception of the holes for the plastic bolts)?
Also, you don't tap the bolt holes, right?

Jim Tansey
02-01-2005, 06:03 PM
I would guess the flanges have a 5 1/2 inch Diameter bore not 6.00 inch, as most times the flanges are glued to the end face of the tubes.

Jim

MarkO
02-01-2005, 07:05 PM
Good observation Jim...
I meant to say routed to the inside (5.5") diameter. I did not plan on mounting the flange to the exterior of the tube. I would definitely end up with some flamges.

spectrum
02-01-2005, 08:49 PM
Marko, Jim is correct, I use a circle cutter to bore a 5 1/2" hole in the botton half of each flange. Both top halves have a 1/4 NPT hole in the center. Part of it is a relic of the manufacturing process and the other is in the first chanber I use it to recycle CO2 and in the second it's the output of the reactor

I know that this is probably way too late for this round, but I think I will go to a reactor when I rebuild my tank in the spring.

How big do I need to go for a 200G tank? How much savings is there on DIY?

2 on the recirculation manifold, 1 on top of each flange, and a pair to connect the top of the primary chamber to the bottom of the secondary.

Dan

I have different sized John Guest's, (1/4" and 3/8").
Are the 3/8" ones the ones connecting the top of the primary to bottom of the secondary? and about how far from the top/bottom of the tubes are they?

spectrum
02-09-2005, 03:51 PM
3/8 are for the connection between the two tubes. I put the far enough away from the edge so that in case I need to replace it, I have enough clearence to unscrew it.
On the bottom of the second trube the same thing, and then make sure you mesh plate is higher that that

MarkO
02-09-2005, 04:46 PM
Thanks.
Should I go with a MAG 2 or a MAG 3 pump?
Also, connecting the manifold to the 6" tube, do you drill and tap, or just glue the elbow to the 6" tube?

spectrum
02-09-2005, 06:15 PM
I'd use a Mag 3, and the manifold should be drilled and tapped.

Looks great Mark!

What do you guys think about tube diameter for a ~100g system. 2 6" tubes seems big but maybe that's what it takes? I have no idea. What about 2 4" tubes, or a 6" first stage and 4" second stage?

MarkO
02-12-2005, 11:39 AM
I can't speak from experience, but if you go by what My Reef Creations says:
http://www.myreefcreations.com/castandard.htm
http://www.myreefcreations.com/calarge.htm
you'd probably be fine with 4" tubes.

MarkO
02-12-2005, 05:12 PM
Does the Mag drive draw water through the bottom of the primary chamber, or does it push it through (up)?

NateHanson
02-12-2005, 05:27 PM
If you push up with the pump, it won't create a brick/type sludge of broken down reactor media at the bottom of the chamber.

MarkO
02-12-2005, 05:50 PM
hmmm, I was under the impression it was the other way around. I figured if it were drawing down through the media, the pump would draw the media into the pump causing it to possibly clog.
I guess I'll hold off drilling that hole tonight.

NateHanson
02-13-2005, 12:37 PM
Yeah, I think we're saying the same thing, but check with Gustavo first.

I'm saying the flow in the chamber should go upwards, exit the top of the pump into the PVC manifold, and return through the pump to the bottom of the chamber.

spectrum
02-13-2005, 01:22 PM
All the reactors I've made flow bottom to top, easier to plumb them and does seem to prevent sludge forming on the bottom

NateHanson
02-13-2005, 07:28 PM
Mark, have you bought all the accessories (bubble counter, solenoid, regulator, bottle, etc)? How much did all that cost you. Others can answer too. I'd probably do the project if it didn't cost $300, but I've been getting the impression that's not too far off. :()

Nate

MarkO
02-14-2005, 12:00 AM
I think I paid about $80 for the tubes, another $60 for other plastic parts, the solenoid/regulator was $135. I've still got to pick up a MAG 2/3 (but I may give it a shot with a leftover Mag 7 I got lying around), but they run $40-50.
I haven't picked up a bottle yet, but I figure that will run $50 or so. I'll build a bubble counter out of spare parts, and I think the ARM might be $15 or so. So to get one up and running, $400 might be a better guess.
(I also bought 3 NPT taps for $25... but I'm a sucker for buying tools I'll prolly never use again :rolleyes: )

MarkO
02-14-2005, 12:05 AM
Oh yeah, forgot about the O rings. I cut my own tonight and it cost me a bit of frustration as I cranked down on the flanges too tight and subsequently cracked the flange. Doah!!!
Anyway just re-fastened it with Weld-on. Seems to be working ok. Didn't you mention there was a place in Lawrence/Andover area for o-rings?

NateHanson
02-14-2005, 12:18 AM
Ha! I did that same thing on my kalk reactor! But I busted the flange with 70 pounds of line pressure. (duh) I just fixed the crack and it doesn't seem to be any worse off, so yours should be fine.

Yeah, I got my o-rings from "Marco Rubber" in North Andover. Every imaginable o-ring under one roof! They gave me a few of various sizes I thought I'd need, and didn't charge me.

Two inlets to the manifold are H2O and CO2, I put my CO2 closer to the pump inlet, most likely does not make a difference
