to see what they could figure out and all the parameters were good my nitrate was at 0 and my phosphate was 0. After talking to them I told them I had Clear Max phosphate remover in my filter and they said that Red Sea would interact with the Clear Max and leach out the ferric oxide poisoning my fish. I'm not sure if this is what happened but I do know that I lost all my fish 3 days into dosing. But it did work I have no nitrate or phosphate anymore.
That's awful, sorry for the loss!
I need to study what Clear Max is composed of, obviously GFO
from what you said, but I don't fully understand the chemical reaction that would cause this. The Red Sea product is by my best guess composed of mostly methanol. Alcohol in general doesn't effect ferric oxide, but a lot of people that use this stuff also use GFO
, so that's why I am confused as to what happened to you.
