how many of you reefers are using a Kalkwasser with your calcium reactor? I was at the LFS picking up some corals when I over heard them talking about a kalkwasser unit, I chimed in and they explained when your system is stocked with coral a Kalkwasser isnt a bad idea. Can anyone really explain about it for me, Do you mix your RO water with lime juice for it? Any pictures would also help a great deal.
Thanks all
