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?
