Sounds like you need to calm down....and leave the tank alone for a few weeks. Maybe you are OVER cleaning. Make sure you have a good filter. We experienced cloudy water after initial setup...but that went away. We now do thorough gravel vacs once a month, only replacing 1/3 of the water, wash the filter media in old tank water while doing the change, NEVER wash tank decs, use dechlorinator for the amount of water you replaced, add aquarium salt to 1 tbs for every five galons. Our fish are healthy and FULL of energy. (and we keep the temp. around 72-75. Our water is clear.
