Minimax Midsize Reactor By texas reefer on 3/8/13texas reefer would recommend this product to a friendI have a 58 gallon shallow tank. 30x30x15 with the sump sectioned in the rear of the tank. Everything was easy to setup. The design is very simp and effective. Only issue I had was with the clamp fitting around the edge of my aqurium since I have a 1" inch brace. The reactor was able to stand without the clamp with not problems. Other then that I am extremely satisfied. I am running bio pellets and it is very easy to control the flow. I will be purchasing two more in the future for GFO and Carbon.
