Corydoras Species Tank

[Barracuda518]

Looks like I have an algae problem developing in my cory tank. I want to catch it before it gets out of hand. Any ideas on how I could get rid of the algae without adding any new fish or disturbing my cories too much? I have seen those magnet things where you have a magnet on the outside that moves one on the inside that cleans the glass. Anyone use these?


Thanks in advance

Yeah they are great work realy well the kids love using them but get a floating one so that its easy to retrive if it comes off. No good for doing the back though!!!!!!
