Looking for 2-3 reactors for my 120 I'm setting up soon. Going to do Carbon and GFO and thought about bio pellets later on. Was originally think just to get 2-3 TLF reactors, but then thought about getting some of the BRS Deluxe's . One thing I do like about the BRS reactor is you can mount them by screws instead of tank mount. My sump will be crowded as is. Was probably going to run off a manifold if possible. I have a Sicce 5.0 (1321gph) . If its not strong enough, then maybe I will use some maxi's instead. Did not know which to get, if anyone has suggestions please throw them my way! Thanks
