Who here doses Kalk? I’m interested in learning more about it. I dose 2 part now but would like to try Kalk. I have read and watched several videos on how to does it and the ATO way seem to be the safest. I have a reef controller that would monitor my Ph and turn the ATO off it the Ph got above a certain number. My biggest questions are how do you know how much to start dosing? Do you start with the recommended does and test a couple of days later to see if it had any affect? Also if using the ATO as the way to does do I have to worry about my pump sitting on the bottom of the container? I use a regular pump in my ATO not the aqua lifter so it sets on the bottom of the jug. Also do I put a circulation pump in the ATO container to keep the water mixed all the time or let the Kalk settle out? Any info would be welcomed.
