I use one of those algea scrubbers that looks like a scrub brush you use to clean tires, but with a nylon pad instead of bristles. Can't remember the brand name but I got it at Petsmart for like 6 or 7 bucks. Cheap and works like a dream :thumb: . The only downside to it is you have to get your arm in the tank to use it , but for as well as it works who cares. Other than that a nylon pot scrubber will work good .
I bought one of those Mag Float things at Petsmart. It was $15 dollars for up to like a 120gal tank. Smaller ones are cheaper. The thing is awesome!!!!! I cleaned my whole tank in just a few minutes and the galss is crystal clear. BEst thing is if the magnets become seperated it floats so you dont have to go digging around in your tank for it. They are great.
