Hey everyone I figured I would start a thread on the new Kalkwasser reactor that I just picked up from Two little fishies! It is the KW Reactor 300, it was 85 bucks from Bulk Reef Supply. I will post a couple pictures soon on what it looks like on my tank and how it works. So far it works great. I have it on the Frag tank to help keep alkalinity levels at a more stable level. Cross your fingers I figured for the price I could at least try it out. More to come!
