Penductors on a Drilled Tank?

[starrfish]

My tank is drilled for both the return and an OM closed loop. In other words, I don't have any pvc piping coming over the top of the tank. There are bulkheads in the holes and jacuzzi jets are screwed into the bulkheads so that I can control the direction of the flow. The main return is a Sequence 4200 and comes through 4 jets high on the back wall (it's a steady return of water - no alternating flow). Then there is a Sequence 3200 driving my OM with 6 jets drilled into the sides of the tank. These obviously have alternating flow. It's a very cool design (thanks Marc!). However, now that my corals are getting big, they are growing closer to the jets and I'm limited as to where I can point them. I would like to have more control over where the flow is directed, and I would like to have more of a "spread" instead of a "jet" of flow. I was wondering if I could install loc line with penductors in these bulkheads to give me control over the direction of the flow and give me more of a spread. Does anyone have an opinion on this? Any advice would be most appreciated.

Thanks,
Daire

Should have asked while you were at my house. I have all that stuff hanging in the basement too!!!! (I don't want to sell but I could have showed you how to do it & yes it can be done) There is many different options, from fan ends, to Y's..... then a little more locline..... to a couple fans ends, to direct flow in two different areas. They have ends to accept the thread size of penductors too. But those penductors are very concentrated in the flow area. They're VERY very in one small area. HTH....Just send me a pm if you like.

Thanks Bri. I should've asked - god knows you have everything down in that basement of yours! I think I'm going to give it a shot. I'm going to order a bunch of locline and just play around with it.

ps...the ballasts are running great!

Isn't his stock room amazing !!!!!!!

My experience was that the penductors had a very wide chaotic flow pattern. Much wider than a Seio 1200, for instance.

 

[starrfish]

Yes! And it's great to have a resident techy to help you put the stuff together!

Nate, that's what I'm hoping for. Did you have the penductors connected to locline? I wonder if that makes a difference.

 

[littlep93056]

I had two of them on linelock , works great The linelock is great because you can point them anywhere you want

The tricky part is going to be matching the thread size, I'm not sure the ID or FPT of the 1" bulkhead is a standard pvc thread size. If it is then your all set as you could use any combination of bushings tees etc. to get to your loc-line. One thing to consider is that unless you do the same to each you'll need to play with balancing out the back pressure or you will get very little flow from the modified outlet (water follows the path of least resistance).
just thinking out loud if you came out of the bulkhead with a close nipple and into a thread X thread tee. That would get you two outlets parallel to the back wall then you could bush them down and add your loc-line.
Another thought is to modify the "eye ball" to take a loc-line fitting.

 

[littlep93056]

The inside thread on bulkheads is standard pvc thread

 

[marco67]

OK I just checked and your in luck, the 1" bulkheads are a std 1" FPT with the "eye ball" removed and the 1 1/2" follow also.

 

[starrfish]

Phew....believe it or not, I think I followed all that. Marc, you're saying I could put a "T" in each of the bulkheads to have 2 penductors for each one? I wasn't thinking along those lines, but that sounds like a good idea - I'll have even more control over the direction of the flow. The tricky part is going to be getting those "eye balls" out because of all the coralline buildup. I'm going to give it a shot. I'll let you know how it works. Thanks everyone.

The only problew is connecting the Penductors to the loc-line , I used 1 inch black hose

 

[starrfish]

Aren't they both threaded? I thought there was a locline piece that had a threaded end?

 

[littlep93056]

i just did some research You can do it by using a double socket & npt connector then the Penductor (female ) on the end of the loc-line

 

[starrfish]

Thanks Mike - that's what I thought. Can't wait to see how this goes.

Just trying to follow, are you trying to do something like this but into a bulkhead instead of drain pipe?

 

[littlep93056]

that's what she's doing

 

[starrfish]

Yes - exactly! How is it working? I think I'll start with 1 penductor for each bulkhead, then expand into 2 (like what you've shown) after I've tried it out for awhile.

 

[Behrmon]

Yes - exactly! How is it working?

Don't know yet, they are on the 150 thats only 1/2 full right now. I will let you know in a couple days.
