Setting up a 50 gallon Lowboy Frag Tank, already have a light (Reef Breeder photon 32 pro). Any suggestions for heaters, frag racks/egg crates, and other things I would need? Also I have two Tidal 75 HOB filters that I had on my planted tank before, I cleaned them out and used alchohol. Would I be able to use these for filtration for the frag tank? Are they good enough? We have avoided a sump because we were nervous of cutting the glass since low boys are hard to find in our area. Thanks!
