NOTICE TO PURIGEN USERS - TRIED, TESTED & RESULTS

[jft]

Yeah I agree purigen , great product like most seachem products, I would place purigen between floss in eheim 2217 canister and that would allow total water flow thru I believe much better than reactor setup, just my Opinion, Any Thoughts?

I am thinking the same, the reactor setup while it allowed for complete exposure to the purigen, after 7 days the reactor completely clogged due to the sponge on top of the purigen and stopped the flow of my canister completely!

I am looking for a way to improve this currently..

Seems like you may need a better prefilter to filter out the smaller particles that are clogging up the reactor. Kind of seems redundant though, like polishing the water so it can be polished....

yeah exactly...I have the following setup:

2.5L Prefilter with 2.5l Eheim Mech Pro going into Eheim Classic 2217 stacked from bottom to top with 1.5l Eheim BioMech (Bottom), Eheim Blue Sponge, 4L Eheim EHFI Substrate PRO, Eheim White Pad (Top), this this goes into the reactor....

Is the Eheim Blue Sponge in your canister the same as the sponge that is sandwiching your purigen? Seems like if it is than nothing should be getting through that would be obstructed by the 2nd sponge

Something else is going on here. There are several vids on YouLube of people with fludised pruigen reactors with nice dark brown purigen. Whether its packed or fludised the water never physically passes through the purigen, as long as it is in contact with water is should suck out the impurities.

no the sponge in the reactor is a coarser sponge, but to stop the purigen i used a 100micron media bag, and pushed the sponge inside like a sock...

the low micron sock got totally clogged, but i couldnt think of anything else to stop the purigen....maybe i should use a normal sponge with a wad of filter floss behind the sponge?

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

It was my understanding that you don't want the purigen fully fluidized but have the flow slow enough that it's at a low boil.

yeah thats what i had in my original reactor! it was "simmering" about 1" from the top of the reactor! but it didnt seem to capture anything, which is what lead me to stuff the media solid in the reactor.
