Don't waste your money. Some people like to take things to the extreme and indulge in all of this tomfoolery with fancy gadgets but I'm a big believer in "biology, not technology". Simply have a sump with an area partitioned off and fill that section with crushed coral. Then, have the overflow run thru that and into the sump. Using this method, you will probably replace 20 lbs every 6 months. And its obviously going somewhere. I still add a weekly dose of calcium and buffer but if I forget for a month, I doubt it would hurt much. Its just my ghetto way of adding a little stability to my systems.
