Sediment filters on water mixing stations...

[afboundguy]

Does anyone run a sediment filter on the SW bin (or even RODI bin) in their mixing stations? Read some stuff saying it's a good idea if doing AWCs and could help keep the brown muck out of the container and curious who is doing that and what micron filter would be best?

I’ve run a RODI canister with a paper filter before to help clean up the reef crystals brown gunk. I sunk the whole thing in the salt barrel hooked up to my standard mixing pump. Looked kind of janky but worked like a charm.

I do but it's been a battle with city water though. They clog up pretty quick IMO. Started with a 1 micron and it was also clogging up the carbon block. I went down to a .5 micron and it still did the same thing. I ended up going back to a 1 micron and have had decent luck on my last run of filters.

I just pour my salt into a filtersock that hangs in my mixing bin. Gets the majority of the brown residue.

I'll have to try both as I get the brown gunk as I use Reef Crystals for salt.

My Town's water isn't too bad. It's a about 250 TDS coming in after the filters (or before the filters can't remember) and then the membranes do a great job knocking it down to under 10.

1 micron is the smallest I would put on my RODI setup and thinking 1 micron would be enough for a filter for the SW jug but might start with 5 or do the filter sock trick.

That's not a bad idea too. I was thinking start with a 1 micron and then a .5 micron after that. The sky is the limit. LOL. How many stage RODI system do you have?

I have a sediment filter followed by two carbon blocks (believe first is 1 micron and second is 5 micron) then two 75 GPD RO membranes (had enough pressure to add the second one without a booster pump and still have 60-65 psi) then a cation resin single stage, anion resin single stage and then mixed resin bed.

The first single stage resin bed (forget which is which) gets used up much faster than the second one and is almost exhausted while the second one is only halfway done. I know it's almost done as the TDS actually goes up after it as I measure before and after each resin stage and it's like 2-4 coming out of the RO membranes and then goes up to 5-7 and then back down to zero after the second single resin bed.

So guess that's an 8 stage setup? Not entirely sure but I have thought about adding another sediment filter and doing a 5 micron then 1 micron sediment before going to carbon blocks.

That's a pretty insane setup! What we do for our tanks. That's great you still have all that pressure without a booster pump and all of the sediment you get. How often do you change the sediment filters? Maybe just go big or go home and add a 20" whole house filter.

Wow! I thought my input water was high TDS! I'm usually running about 90-95 coming from the tap and 1-2 coming out of the RO membrane!

That is so odd, my DI resin does the opposite! I don't even know the ratio yet. I've changed my 2nd resin 3 times while I can't even tell where the 1st one is used up to...
