I am trying to get my fish only tank (well, fish + crew) acceptable for other inhabitants. I do not use RO water, but use water filtered and deionized with the Aquarium Pharmaceutical's Tap Water Purifier. pH is at 8.3, amonia, nitrite, and nitrate are at 0 (well, nitrate is actually just below 0.2 on a low range test . . . this is the lowest possible measurement on the SeaTest kit). Calcium, though, is low. When I tested about a week ago it was at 150. I started adding C-balance daily and it is now up to 180. This is still way below where it needs to be, but I expect that this should be raised slowly to prevent pH spikes and other possible problems. Is the C-balance a good choice to raise calcium as suggested by my LFS? If not, what is the recommended method and product(s) to do this? How fast/slow should this be raised? Should I drip Kalk instead or in addition? I really don't see that I have a good place to set up an ongoing drip, which was why the C-balance is appealing.
