As many of you know im dissabled, so due to being in alot of pain i did not do a water change or gravel vaccum for two weeks. NEVER will i do that again. After doing a 30 percent water change, and a good vacum my tank was so stirred up I could not see anything in the tank. I had a spare filter so I hooked that up, and the tank is starting to clear up. Only 5 barbs, and 2 tetras, so i must be feeding to much, that is the only thing i can think of. my water parameters are great.
