Can I circulate salt water through my DI cartridge to remove phosphate from my tank. I have RO/DI for the make up water, but still get green hair algae and those pesky little green anemone looking things. Forgot what they are called
I've read of other people adding a canister of gfo to the ro/di...but if you want to run it on already mixed salt water than you can just use a regular reactor.
Daw, that phosphate is not from your RO/DI, it is the guy in the mirror overfeeding or not checking or knowing the phosphate levels in the food they feed. Reefers like to blame everything about phosphate other than the hand that feeds it to the tank.
