Are there any all-in-one, HOB GFO reactors that anyone here would recommend for a 75 gallon fowlr? I do have a sump, but I'd rather not put anything else in there, if possible, so if there is a unit suitable for this size tank that I could hang on the back, that'd be great, particularly if it comes with a pump. I'm not sure what the flowrate should be. Thanks!
