Hey there Mike, I know this is a little bit of an old post but it came up when I was looking for a solution to put the BRS Carbon/GFO deluxe reactor into my RSM 250 setup. Everything I've seen thus far had it setup in an in-cabinet sump, which I do not have. Could you elaborate on how you have the reactor in your media chamber, if you had to mount it any special way or if it is just sitting in there on top of the pump. Also, you mentioned needing extra elbows? Do you remember which ones you needed and how you had to use them to get it to work in the RSM 250? Is it worth paying 2-3x for the Sicce 1.5 vs the MJ1200 that they bundle the deluxe reactor with?
I'm dealing with some phosphate probs, been using CPE up until now but its only 1.5 months in and I'm trying for a little more budget-friendly Carbon/GFO option for the long-run. A reactor seemed to be the best way, but I don't have much room to do a 'hang on back' option where the fans are. And I'd rather not mount it to the wall outside of the tank. I thought about doing it in-cabinet but then the water pumps out and down and back up, not sure how much head pressure that would take. Any advice is appreciated. Thanks!
