Raising DKH

[reefertank]

So very established tank over 3 years. I stopped doing a lot of water changes from 1 a week to 1 every 3 months. Corals haven't grown and I get that is expected. Fish are all healthy and doing great. Anyways I just hooked up a dozer and did a water change of 25%. The water change raised my dKH from 5.1 to 5.5. Now the dozer has brought it fow 5.5 to 6.5 in a week. Am I raising to fast I get that slow changes are best. Is going up 1 in 7 days to fast? Oh and all other parameters are perfect except calcium which is a little low and I'm slowly raising that with a dozer as well.

You are doing fine raising it at the speed you are. Stability is key, so slow changes are good. The general rule it to raise Alk no more than 0.5dkH per day.
