my sps reef tank calcium level keeps droppin and i am going through about 1 tub of calcium every other month. i plan to use a pasta jar and drill/modyfy it. has anyone ever done this? and does any one have any tips?
I was wondering wether or not to buy a deltec
but they are so expensive. I have heard of people making them so if I can do it this way then I will. if not, it'll have to be the deltec.
