My PH and dKH have been a little on the low side and I have been looking in to the Two Little Fishies Kalkwasser Stirrer / Reactor as a solution. Right now I have a 75 g total system, mixed reef with not many SPS corals but I plan on adding some Acro later, currently my Ca is around 460-480 so I don't need it for that. I was wondering if i do decide to go with kalk will it add too much Ca to my current system and hurt it? Will kalk raise my PH and dKH or just maintain them? Are there any other benefits my LPS, softies, fish, and inverts my receive from adding it or is it mainly used for an SPS tank? And could I just connect it to my ATO or does it need to be constantly dripped? Thanks
