NOTICE TO PURIGEN USERS - TRIED, TESTED & RESULTS

[administrator]

Thanks OP. GTK.

yeah thats contact time, because Purigen is a scavenging resin it needs slow flow and very high contact time.

I emailed seachem, who were very helpful and they advised that if ti was fluidized the flow should not be any higher than 3-400lph, otherwise the purigen is just thrown about by the water, that explained the purigen in my fluidized reactor not actually doing anything.

I would be interested in seeing the fluidized purigen with the dark colour as i have not seen any, maybe i was seeing videos of newly fluidized reactors...do you think you could post a link or 2?

thanks

I bet he doesnt even have a 100gph going through that 10" X 2.5" reactor housing though.

I think you just had too much flow through your large reactor housing and it slowed down the flow enough when you packed it in to make it effective.

That's more like what I was referring to, many of the ones I've seen run even slower than that.

yeah exactly, i had unthrottled classic 2217 powering the reactor

it did nothign!

I am still puzzling about how the hell these guys are stoping gunk and crap building up in the reactor....

also i was thinking to throttle it back without hurting my canister, i could use a Y to split off some of the flow, and use a tap to dial the flow back and a second Y to rejoin the reactor to the main outlet!

Sounds like a good idea but I would be a little worried about the 2nd Y, personally I would just take the outlet from the reactor right back into the tank so you wouldn't have to worry about it feeding back into the reactor.

yeah i see what your saying, but i thought that the pressure and flow direction would have stopped that!

good call though, I have a spare eheim fishtail outlet i could use for that
