A very short over simplified version of a long discussion: Organic waste present in your aquarium exists as acids, which remove carbonates. Carbonates make up alkalinity. Calcium carbonate is the dominant carbonate buffer in marine water. Testing for both alkalinity and calcium is necessary to maintain the proper balance of calcium to all the other buffering ions. Without this balance, you don't really have "saltwater", you just have water with a bunch of salts. For example, you could add table salt to freshwater and increase the salinity to 1.024, but that wouldn't be "saltwater" for our purposes.
No, there is not anything you can add to the tank to release calcium at the pH levels we have in marine tanks. You would have to lower the pH to the 7.4 range. Generally speaking. (Which is why crushed coral is a decent buffer in freshwater tanks.)
Also, it is important to recognize that you are not adding a "pH buffer". You don't want products such as pH Up etc. You are adding BUFFERS. For example, I use Kent Marine Super Buffer DKH for my buffer. I use Kent Marine Calcium Chloride for my calcium supplement.

Sorry to tell you this, but you can't keep a Mandarine in a 29 gallon tank. They require populations of copepods and amphipods to survive which can not be sustained in such a small tank. A tank upwards of 125 gallons or larger is necessary for this small fish. As an alternative, check out some of the Fairy Wrasses, which will provide you with some amazing color patterns (at a cost).
