Salty- my phosphates are zero since i have gotten my new test kit about 2 weeks ago. I check once a week, My nitrates were high awhile ago but i have got them down to about 10ppm and staying there for about a week now. It may be overfeeding im a sucker for feeding my fish. I know they are opportunistic (that a word?) feeders and will eat whenever they can but again in my research there are so many different opininons. Some say twice a day, others once where some say once every other day is fine. Is it true also that frozen foods dont add as much if at all any nitrates to the water? I read that somewhere. I feed Prime Reef flakes once a day, and mysis and cyclops shrimp once in awhile to my fish. Cyclops and mysis to my corals with phytoplankton i believe it is called, mixed in every third day or so. I siphon out my tank every day, wether its waste or algae on my sand. Lately the cyano seems worse. Could keeping my lights on too long be a factor as well. I tend to turn them on before i go to work around 6am and sometimes leave them on over 12 hrs. If so i need to get a timer for my lights.
