First of all, for anyone to help you properly we need to know the ph and alk levels of your tank. Adding a bunch of baking soda and nothing else is not going to solve your problem, it will just throw things more out of wack. Are your corals and clams growing? Is your RO unit working? If you live in a place with high mineral content it is possible that your RO membrane is clogged. Test the RO unit for calcium. If the RO is working fine and you want to keep it simple, which it sounds like you do, (no reactor,doser, or stirrer)here is what I would do. First of all I would switch salt, Instant Ocean is tried and tested with buffering capacity. Secondly, I would do a large water change(at least 50%) after a couple smaller ones(25%)to get your animals used to the change in salt/chemistry.Thirdly, take a five gallon pail, mix kalk accordingly, and drip kalk to match evaporation. Your aquarium probably has little demand for calcium so this should suffice.
