calcium Help

[helpme74]

Ok I have a 75 gallon reef ready tank with a 25 gallon sump. I use about 5 gallons top off water a week. My calcium goes up a down I would like to do something to keep it steady all the time. But I don't want to spend a lot of $$$$. And I don't want to do anything that will affect my water parameters.
