I'm relatively new to salt water aquariums, about nine months. I thought all was going well. The water was clear, fish seemed happy, and the live rocks looked like when I bought them. I then started testing for nitrates, nitrites ph, and ammonia. Ammonia was 0, nitrites were 0,ph was 8.0.but nitrates were off the scale. I started water changes once a week to bring the nitrates down to 40mg/l. I normally would run the light for about three hours a day ( 65 watt 50/50 compact ) in my 29 gallon bow. The rocks were starting to and did turn black. I was told to run the light for 11 to 12 hours a day. I've been doing this for about three weeks and not much improvement..I can see red and green (fuzz ) growing on the rocks along with algae blooms on the glass. My local fish guy gave me a product to replace the essential nutrients in the water. Not much help. I would appreciate if any one could help my tank.
