I have 2 reef aquariums mixed with shrooms, zoos, and some softies. I am looking at ideas to automate calcium/alk dosing on my larger 100 gal reef. I currently dose all topoff with Kalk, and add turbo calcium rarely as needed to keep calcium near 410-420ppm. I've been reading a lot on different methods, I'm looking for ideas on what works for you. I would just like to be able to go a few days at a time without having to refill kalk jugs etc.
