No supplements at all? where is the calcium in your tank coming from? Do you have a calcium reactor? I'm thinking about getting one of those to keep my calcium levels up instead of continuing to spend money on a constant supply of calcium additives.
Edit: I just looked up the Seachem Salt you said you are using and it seems it contains all the calcium and alkalinity you need. I might look into using this salt mix instead of the Reef Crystals. I'm just not sure if it would be worth the constant water changes it seems like I might need to do to keep the levels up.
