I think I killed everything in my tank first time in the saltwater aquarium. started with a marineland 150 for a 29 gallon tank everything went ok for the first cycle. Bought my first corals and fish.. another week everything ok...out of nowhere nitrate out of control, and water very cloudy switch to a fluval c4 but now I see one of my clown fish a the bottom of my tank. did I just started all over by switching filters
