I'm going by what Drs. Foster & Smith told me when they called me. Nothing else (visible anyway) was affected by it. The red slime is history, tho. I have cut back on how much I feed (feel sorry for the little guys) and have new tubes coming tomorrow for my older PC fixture (the other one is less than a month old and the difference in light intensity is dramatic). I also cleaned out my other canister filter. The guy I bought this system from, about 10 weeks or so ago, told me that both canisters needed cleaned. I cleaned one within a couple weeks of getting the system and wanted to wait before cleaning the second because I didn't want to disrupt the bacteria in both filters at once. Yeah, I know, I should use a refugium instead, but that isn't going to happen any time soon. I added some De-Nitrate to the canister when I cleaned it, as the nitrate has been running around 15-ppm. Hopefully, cleaning that filter and adding the new agent will bring that down. I'll test it in another day or two and see what the nitrate is doing.
Ammonia = 0
Nitrite = 0
Nitrate = 15
Phosphate = 0
