Public aquarist's RODI questions

[SonoranSwimTeam]

Are there any public aquarium keepers out there, that can point me in the right direction for implementing a new RODI system? I go through about 5K gallons a week and it seem that a home RODI unit is cost and labor prohibitive. I have a water softening (cation,) followed by carbon and a large reverse osmosis (w/booster pump,) and reading zero TDS. However, I've been dealing with a nasty silica problem for some time now. It build up on the pumps, holding bins, causes the calcium and magnesium to fall out of mixing solution and low pH. I got the RO water tested, and the recommended silica is 0.001ug but the water is reading at 14,000 ug. Thank you!

@Jay Hemdal any thoughts?

@Jay Hemdal any thoughts?

Sorry - no, our RODI system only makes about 500 gallons a week using a large hobbyist system with a booster pump. I don't know how to make 5000 gallons a week of coral tank quality water. Our amphibian exhibits use commercial RO water, but there is no DI component for that, and you need that to reduce silicates I think.

Yeah, it's quite a bit of water. I've seen pictures and diagrams of large anion filtration units but none in use, let alone at an aquarium. AZ has some pretty tricky water to deal with

I would consider a Spectrapure producer. I don't sell these but I used them in the past. These are a very good value for the production rate and are generally the largest units you can get without a booster. Spectrapure is also local so they get my vote. Spectrapure can also make custom boosted untis. I have seen 20,000 GPD units that they have built when picking up my order from their warehouse. The producers are made to order but the last one I ordered was about $1800 for 1400 GPD model no booster required. https://spectrapure.com/pages/lab-and-commercial-systems
