BRS dual reactor

[daplatapus]

If you have the room, I'd recommend going 2 separate reactors as well. Sometimes you need to run more carbon (like when you have some chemical warfare in-tank going on), or you've got your phosphate totally under control and don't need to run much GFO. Pretty easy to do either with separate reactors, but possibly a waste with only one. As mentioned each run more efficiently with different flow rates. And depending on what's going on in the tank, one may get exhausted quicker than the other.
