I hope I'm doing something wrong and there is a solution to the constant buildup of this kalk paste in my sump and float valve. I make kalk water in a 5 gallon water container, 2 teaspoons of kalk per gallon of RO water. I give a quick mix and let it sit for about 3 days for the buidup to precipitate out and settle at the bottom. After 3 days the water is still cloudy but not as bad as when mixed. I syphon out the water into my ATO container, carefull not to disturb or suck up any of the paste at the bottom.

I have a gravity fed ATO and after a day or two there is ALOT of kalk buildup at the surface of my sump and around my float valve. I try cleaning it every other day but once disturbed the paste sinks and builds up at the bottom of my sump near my return which in turn shoots some into the tank.

Where am I messing up?

Is there a DIY container that will allow me to bypass putting it in my ATO container an constantly drip kalk and minimize this buildup?
