And stock up on lots of vinegar if your going this route, your going to need it to clean your pumps.

Myka his alk levels are within reasonable range, if by "doubling or tripling" the 2 part until calcium is up to 400ppm the alk will be through the roof.

Start by raising Mg levels back to 1250-1300ppm... wait 24hrs and then test all levels. Raise calcium with turbo calcium until you reach 400ppm, wait a few hours and then test. Add alk if needed to keep at 8dkh.
Even if you go with the calcium reactor you need to do this before hooking the reactor up
