Ok what am I doing wrong? I have fissiden and christmas moss in my restarted tank. I know Fissiden's can turn brown and then come back but I did not think this was so with most moss. I am using EI regular daily. 50% wc weekly and the Par says the middle of the tank is 50 and 38 at the bottom. O, O, 4 ph 6.5 Temp 80
