I am in a big debate here on what to do. I dont really have problems with Cal and Alk, however my test kits conflitct from time to time and I do dose both somewhat often. I have a co worker looking to part with a Calcium reactor that I can get at a decent price. Should I buy one just to have one, or will I see results having somewhat consistant Cal and Alk levels? What do the experts here advise?
