Hi, Odie. We run a My Reef Creations CR that is a single chamber holding 16 pounds of A.R.M. It easily supports a 300 gallon colony grow out system. It is very easy to hook up and tweek and runs with minimal maintenance. We took a chance at www.myreefcreations.com with the oversized reactor and a twin injector skimmer powered by a MAG24 on this system. We have no regrets whatsoever
and would gladly sell My Reef Creations skimmers and reactors exclusively if given the chance (hint Andy!). Most highly recommended.
I have a dual chamber CR that Andy built for me, works like a dream, I don't add two part any more and my alk/calc are dead stable. Great service too, I think he lives on email because any question I asked seemed to be answered within minutes, definite recommendation
