I am looking to start dosing kalwasser for my tank. As I am struggling to keep Alk above 7 dKH. I have a nuvo 10 with with LPS/Softies. I have been dosing Seachem Reef Fusion 2, however that was 2-3 ml a week (stopped this week to measure Alk demand, seen below). I'm hoping to keep my Alk at 9. But my biggest goal is to maintain it at a certain level, rather that having these steep fluctuations I'm currently experiencing (in the past Alk has gotten to the low 5's!). I measured my rate of evaporation over a 24 hour period, it's approximately 800ml a day.
I have tested my tank for the past 5 days to get my Alk demand:
March 1st - 8.3
March 2nd - 7.7
March 3rd - 7.3
March 4th - 6.7
March 5th - 6.4
Using the Reef Chemistry Calculator I got the following dose to raise my Alk. Stating to add 7.9 ml to get my Alk from 6.4 to 9. However I am unsure how much to dose on a daily basis to maintain 9 dKH. I am planning on using a dosing pump with a separate container of pre-mixed kalwasser (thinking of using the BRS kalwasser mix).
Question: How would I go about calculating the daily dose for Alk to maintain a level of 9dKH?
Some other information I think that is useful: Mg has been 1230/1260 and Ca has been 420. I use reef crystals for my tank and do about a 2.5g to 3g water change weekly. Going to tone it down to 1-1.5g weekly water changes. I think that has a factor or my Alk issue. Tank has been going since August 2022.
