So I run about a 50g total system, and I’m newer to the sump life, but I had just been handing a media bag with my iron oxide phos remove (extrax phos) and I was getting very little movement in my number. Like .01 over a week. I used it in my old system with a hob filter and it was very effective. Anyways I was looking into the brs mini reactors but I was hesitant just because it was something else I had to mount. Anyways found this at lfs and they showed me in there demo tank. And I was sold. Ever since my medias have been much more effective. Not a terrible price point, and majorly adjustable as far as flow goes
