Ok so i dose saturated kalk to the evaporation limit of my tank. My thought is if i used a kalk stirrer and cycled saltwater from my tank through it as needed i would not run up against that limit. I'm sure there is a reason not to, but can anybody tell me why we don't do it this way. I mean even if I had to pump a hundred gallons a day through it it seems to make more sense to me.
