GFO after RO/DI ? Filtration experts needed!

[Flippers4pups]

I'll be posting this in the reef chemistry sub forum as well.


Okay filtration experts, I'm posing this question if anyone has ran a chamber for GFO down stream of your RO/DI unit after your last DI chamber? Reason? Silica!

As we know, silica is negatively charged in a PH between 3 and 8 and is attracted by anion hydroxide resins, either in a mixed bed or a Anion bed. When nearing depletion, the resin starts to release Si back into the water. I think I got that right, correct me if im wrong. Lol

My theory is if you used a bed of GFO down stream, wouldn't this catch this any Si released?

Anyone do this? Is it overkill?

Hey Don. This is high level stuff. I hope you get a good answer here, but I would contact Spectrapure if you don’t. Good luck!

Never thought to use GFO in my RODI system. As far as silica goes, not sure if it’s a marketing gimmick or not, but I do use Spectrapure’s SilicaBuster DI cartridge in my RODI system.
