pH and Cloudy Water
Hello Angel...
I've never used chemicals in my tank water, because all tanks run a little differently and you never really know how chemicals will affect the water conditions.
I've never worried about pH, hardness or any of that stuff. I just treated my tap water for chlorine, chloramine and ammonia and put it into the tank.
So, toss the chemicals, don't test the pH anymore. Do treat your tap water, change at least half the tank water every week and add another power filter to the tank for a few days. An HOB is good and just fill the filter with some polyfiber. This stuff is very dense and will catch all the small particles of plant and animal material floating in the water. I've had cloudy water in my tanks from time to time and follow these steps to clear it up.
