Yes I have thought about it! I’ve heard good things about avast products and was planning to utilize that for the ph offset that a calcium reactor makes! To be completely honest, in all the research I’ve done, I kinda skipped over kalkwasser because I didn’t realize the benefits that it could bring! If it’s not too much to ask, could you enlighten me a little bit on it’s uses?Have you looked into a Kalk Stirrer? Kalk is dirt cheap and the stirrer from Avast Marine is just over 200 bucks. Unless you have or are planning on having a high demand tank...take a look. Only downside of a Kalk Stirrer is if your evaporation rate is too low to accommodate the Kalk dosing needs or if your Alk and Ca uptake is more than your kalk stirrer can put out (see point 1)
