150gal ZEO que dramatic music

yeah, i had did the phos RX before, and it worked well, i think it was chowder that had a DIY post for this kind of RX.

mine worked well, only thing was it was hard to start the primeing of RX as well, when i glued it, i didnt put a sleave inside the RX for the zeolites, and they would always get wedged inbetween the red plastic bottom and the side of the RX when priming.
