Who uses rowaphos

[Craigdillman]

I use it in my tank, works awesome was skeptical cause you need so little.I went through it initially a little quick cause my phosphates were higher around .25 but now its leveled out at 0.05 or less on the ELos test kit and noticeably more coral growth just in the last 2-3 weeks

I just run it in my canister filter beside the carbon as a media reactor
