Yea Ive been doing a lot of research on it. The tanks almost two months old. The last test i did came up with phosphates at 0-.25 the colors were not to clear to read. None of my other readings were bad at all. I have two circulation pumps running one blowing the length of the tank behind my LR and one on the back of the tank blowing straight forward. I plan to buy another one to blow the length of the tank from the opposite direction. I started out with tap water I know bad idea but I have been using store bought salt water since i noticed the algae problem and I am looking into Ro Di units. As for a clean up crew I have about 15 snails and 15 hermits, also an emerald crab,a cleaner shrimp, a red knobby star and a orange diamond watchman goby sifting through the crushed coral.
