phosban reactor

[exoticar]

for those alittle more advanced, I diy'ed a phosban reactor out of an old di/ro. Modified the internal canisters (took out the felt on the bottom and top) for waterflow. I used an mj600, an mj1200 and a higher output pump. I can not get the GFO to tumble! i reversed the lines into the DI/RO. I also aquired an aquamedic phospate filter and tried that, still no tumble. does it matter if the gfo tumbles? any ideas?

The brs reactors are the same as the DI canisters, with the insert. 3 sponges, 1 at the bottom, and 2 at the top for GFO.

Post some pics of the cartridge, maybe we can figure out why it isn't tumbling

i have to break it down, the cartridges are spectrapure, they had some type of felt/cotton on the bottom and top. I removed both top and bottom. i placed a foam disc ontop to allow only water to flow, not the gfo, and on the bottom where the cap is, i used mesh from a charcol nylon bag. the water flows on the outside down and thru the cartridge. i also have the aquamedic set up the same way, no tumbling. i thought it might be not enough flow and tried a large mag drive

Sounds like u got it right. I run ROWAphos and no problem with tumbling...
Tapped off my return pump. Valve just barely open.

Only thing I can think of is the flow is backwards

i tried the flow both ways, i have a feeling it might be the gfo, its the only thing i can figure. presently have pura phoslock. i have a container of BRS. i will give that a shot tomorrow. the mag should be blowing it all over, but its just sitting there. round 5 here we go.
