so still battling cyano on sand and some rocks. it says excessive nutrients or low flow possibilities or new tank. Well my tank is somewhat new and I have been feeding one frozen cube in morning and one in morning. I don't think that's excessive with 5 anthias, 4 tangs and a clownfish. Should I just let it ride? Vacuum sand 5 gal once a week? I boosted the MP40s to reef crest 70-80% but I don't have a ton of rock so flow shouldn't be issue.
