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

As I recall mosses much prefer temperatures lower than 80F. I know that Java Moss does poorly in my tank, which tends to be 78-80F most of the year. If you are heating the tank you could try it with the heater off for a few days.

I have fissidens in a 60 I cannot kill. 81F, EI and lower light.

CO2........

That's about the only obvious thing/difference.
Moss does not do well with poor CO2.
