Hello all, I've been having problems with various types of algae in all of my aquariums, but especially my 20 gallon planted tank. All of my tanks get 50% waterchanges every week, I dose Easy Green once per week, photoperiod is between 8-12 hours (depending on the tank), nitrates beteen 5-15 on all tanks. All tanks are over a year old. My 20 gallon is the most baffling. The tank is running c02, weekly ferts, surface covering plants (the middle and bottom of the tank are quite dark), the plants all grow like weeds (I am removing around 1/4 lb of plant mass per week). And the tank is overrun with hair algae. I have to spend an hour cleaning the stuff every week to keep it from filling the tank so much that the fish are restricted in swimming area. It is growing across the gravel like a super-speed lawn. It is growing on rocks and the glass. I am at a loss. As for my other tanks, I have a 75 gallon running 15 watts of lighting in a dark room and it is covered in diatoms. All of my other tanks have diatoms, bba, cyano, lots of hair algae, or any combination of these. Any help would be appreciated, I am really not sure what I am doing wrong here. Thanks.
