Greetings everyone. Thank you for such wonderful forums. I have learned quite a bit. Many are saying that whiteish cloudy water is due to bacterial bloom in a tank, but I have no increase in ammonia or in nitrates or nitrites. I have been doing 20 to 30% water changes 2x per week and the water is still bad. I have 5 guppies and a pleco in the tank, and I am not overfeeding that I know of (tiny pinch of food every other day). I was using the filter system with the Eclipse 12, but tried a little bag of chemi pure in the filter system, replacing the cartridge for a short time. Still no change. Is there anything I am missing? My pH is 7.8 right now and the water is cool. I don't have a heater or thermometer in the tank since they didn't come with the system. I am willing to try just about anything. Thank you for any help you can giv eme.
