My 5 gallon hex has a huge algae infestation... I wiped it down less than 3 days ago and its back! and bad..... the tank is near a window... but its the only place availabe for it because my parents said I can only keep fish in my room and I already have 3 tanks so there's not a lot of space. anyways, I THINK the tank is fully stocked... with two bamboo shrimp and 2 zebra danios, even though I have never ever in the 6+ months of keeping them ever seen my shrimp poop. anyways, I was thinking of resorting to pest snails or something... Id add a mystery snail but I think that would be overstocking the tank a bit. what should I do? I really don't feel like scrubbing the tank down every few days. anyways... I videotaped the problem so you can see how severe it is. The video is currently uploading, so ill post the link in a little bit.
