Using kalk water only for topoff?

[Aquattro]

Mason, the way I add kalk is with a float valve. All my makeup water was full strength kalk. When I used only kalk on my 75g, I would go thru about a gallon per day. Never had a pH problem. Your levels are fine now, so dosing full strength would probably be fine. Do you have a float valve setup? Or how do you normally add top off water?
