Ok, this is not a fish life or death problem, yet. Cause it has been more than a week and have lost zero fish from it. Here is my problem, I have a brownish to almost light grey color of water. My fish are still active and seem healthy(platies and Tetras). Unlike before when I did a water change I stired the gravel too much opening some gas pockets resulting into very bright white water causing some fish to kill off. That got all cleared up. This is something different. It is like there is something just circulating throughout the water like very small particles . My water filter(Whisper) is working fine, but when I look at the tank I can actually see the current of the water by the constent streem of brown particle water. I have changed the filter and cleaned everything out. I have tried water changes everyday. Nothing is working, the guy at the pet store said it will clear up eventually, (Whatever). Please help I am out of options. Maybe I should leave the carbon out of the filter? Just an Option? Thanks to whom may reply!!!
