best calcium reactor ????

hey every body as some of you may know i am breaking my tank down to restart it due to real reef rock leeching phosphates and killing thousands upon thousands of dollars in live stock and i kinda want to try a calcium reactor because b ionic is just getting much to expensive i was looking at the geo line of reactors maybe the cr624 and i was just wondering if this is the best reactor and also my tank is 200 gal and will be mostly sps dominated


and also what other things would i need to buy to get this reactor running?
please list products
thanks !!!
