I am running a 30 gallon supposidly reef tank. My readings that I can account for are, SG
1024-1025,nitrates 0, nitrites 0.10. ammonia 0.10. First my tank was struck down with Ich, treated with exodin. since then I have done a few water changes but my corals still don't look healthy. My fish,1 yellow banded maroon clown and 2 green cromis seem to have made a good recovery and are starting to do ok again. I also have 1 Scarlet shrimp, 2 camel shrimp, 6 red hermits and 3 turbo snails. I cant get ammonia level to zero. Fairly new to hobby, still learning. Water changes using RO
water, approx 40 lb live rock,protein skimmer and powerhead. Also have some brown algae coating live rock. Where am I going wrong.
