I am in the process of starting a marine tank. I went and bought all the necessary equipment from my local fish store (Protein Skimmer, Hang on Filter, Powerhead for extra water movement, Dual Light, and so on) I hooked everything up, added pre-mixed saltwater, let the temp adjust to 77, and then I went to the store and bought 15 lbs of live rock(I was told it had been in the store long enough that it was cured and good for immediate induction to the tank) and a reef substrate. It has been three days since I added that and I have seen almost no change in any of my levels (pH, ammonia, nitrate, or nitrite) However there was green long hair like algae on the rocks and it has now turned rusty, brown. What is going on?
