Zoans not doing so well

[pencile]

I have been carbon dosing for the last 3 to 4 months in my 120 gal tank, not a lot but around 4 mills a day. It seems to be working really well for the sps's but here lately I have noticed that my Zoa's have been declining in health for some reason. Can the carbon dosing be doing this?
Only other change came from phosphates which where high, around .07 had green hair algae problems as well. So I have since gotten a better R/O system and better phosphate reading as well.
Cal 430
Alk 8.1
temp 78.3
phos .03

Have you been using any coral food? Is the GHA still present?
