well stop feeding crappy pellets and start feeding real food. lol

Pellets, flakes, etc. they all contain fillers and preservatives. I feed only live or frozen. Frozen gets rinsed of course. I feed MASSIVE amounts of foods. If feeding huge amounts of foods is what gave people hair algae I'd have a shag carpet in there. But I don't.
I'll dig up a great article in a minute here. Be right back ;)
