Finally was able to hook up and get my new Jasper Reactor dialed in. Not only was it easy to dial in, the stability of my system has been great. I purchased the larger single stage reactor. My tank is a 60 cube, SPS dominated with a 50 gallon sump plumbed out onto the patio.I have seen some very nice growth from all corals. Justed wanted to say thanks to Jasper and if anyone one is in the market for a Calcium reactor, I would look into his units first. Well worth the money and the craftsmanship. Thanks again.
