I use 2 phosban reactors on my system. I have phosban loaded into one of them and carbon loaded into the other. Our club is getting ready to do a group buy on the bulk version of the phosban media that works out to be something like 10$ per POUND.
I've heard that you should ramp up and be careful because on a dedicated SPS
system you could throw the system into a tizzy by running too much phosban too fast.
