So its now spring and I am having an issue with two of my tanks that are in direct sunlight. The tanks are cycled and cleaned on a regular basis but I am having an issue with green water and its getting rather annoying. This wasn't an issue until I moved to my new apartment, where the tanks are its often in contact with direct sunlight and it can't be moved. Its getting ridiculous, I do a 100%+ over the course of two days and its an issue again the next day so I am assuming the cause is algae because everything else checks out fine. The two tanks that have contact with sunlight have this issue and the other two don't.
So are their any products I can add to the tank without damaging the biofilter like Tetra Algae Control or something? I would like to pick something up today so any help will be appreciated.
