I have been using kalk on my ATO for months. I could never get my parameters to stay stable. I also could never get my alk to go over 7.3. So last week I was super busy I finally got the job if always wanted. Yesterday I did my water change so today I tested for the first time in over a week. My mag is at 1400 my cal at 440 and my alk at 9.3. It's crazy like my kalk is finally working or something.
