HI, I have a weird problem. I have 20ppm no3 its off the charts. I also have po4 around .04PPM I have 0 algy in my tank and also cannot grow chaeto. I tried dosing iron but it still didn't help with the chaeto. I want to grow the chaeto to bring down my n03. is there anything wrong with my tank in why I cant grow chaeto. I have it in a chaeto reactor and run the lights 24.7 weird..
