I can’t really answer too much as the setup I’m using kalk on is newish. I haven’t bothered testing in a while, and don’t run any controllers or monitors for ph so that stuff I can’t answer. But what this is what I can answerHow much are you dosing, and do you see a difference in ph, stability, growth etc
Mixed reef - mostly lps currently but a few sps and zoas and mushrooms.
50g display 10g sump approximately 50g volume.
70w mh with 2 reefbrite lumilite strips. (It’s technically temporary until I buy a new light but I’ve been using it on the old biocube for years, the new setup replaced that old tank) but it’s actually growing corals right now top to bottom.
Kalk mix - I use a 5g bucket to hold my mix, I started with 1tsp per gallon and am working the way up to full saturation slowly as I add more and the stuff starts growing. Currently at 7tsp/5g
Dose is around 2000ml day i adjust it up or down slightly with changing evaporation/seasons . Kamoer x1 dumps it in with 12 separate doses from 12am to 11am.
Everything is looking good, like I said corals are showing growth and good color. Stability is good enough imo, it’s a consistent dose. Adding it at night will help raise the ph so that’s why I do it. Is it 8.2+ Consistently probably not. None of my tanks suffer from super low ph as it is so it’s as good or better than my other systems I assume
