So my tank is about 1 year old now and I have some mushrooms in it and I would like to keep it soft coral dominated, but I would like to get one centerpiece branching sps coral. The tank is 29 gallons, has the reefbreeders value LED fixture over it, and I do a 5 gallon water change with reef crystals every other week. The tank is sumpless as well (the location wouldn't allow for one). I'm curious as to if I would be able to keep a sps coral in my tank, and if so, what type of calcium and alkalinity supplementation should I do?
