I have a 77 gallon tank which has been cycling with 2 black mollies in it for about a month and a half, everything was going great and i came home yesterday and the water was cloudy and there is brown and green algae covering everything. I tested my water and everything was fine except my phospates were high. My filter is an emperor dual bio wheel model, but i dont' have a skimmer yet. Any ideas as to what may have caused this phosphate spike, and so much algae to grow in a day? Thanks in advance for any help.
