it does give off an odor until it is completely dry.. i got paranoid about mine and have soaked it in 3 capfuls of prime in a cup, then air dried it and re-soaked it, because it still smelled..

then i realized it was the prime i was smelling.

I soak in a glass 1 gal jar ( 1 - 1 mix ) and place an open airline into the bottom to keep the purogen suspended, takes an hour or two and its back to being white, I then rinse with fresh water 4 or 5 times and on the last two rinses add prime maybe 2 teaspoons. I then re rinse and put it straight back in the tank, so far the discus and cherry shrimp have had no problems.

On the phone with Seachem technical support today. After regenerating the Purigen you are not supposed to ever let it dry out or it can crack. Using it then could leave a precipitate type dust in your tank. I'm believe this is what happened with my tank. Used Seachem Clarrity and hung a Marineland Hot Magnum with a micron filter on my tank and it cleared up.

Discus Paul posted earlier that after regenerating it let it soak in de-chlorinated water until you are ready to use it again. It would be a good idea if Seachem noted the need to keep wet after regenerating on the product label.

Since all of you know so much about this product, is there anyway any of you know about this type of algae? I know one guy said H2O2 for the cure but that scares me with my discus being in there... any suggestions?

So to resurrect this back from a slight hiatus, how do you know when your Purigen needs to be recharged? Is it when it turns all brown?

Yes, but don't leave it till it gets very dark brown/blackish. It will then have already begun to lose it's effectiveness to adsorb undesirable material if you do, it will take longer to fully re-generate properly, and I expect it would have a shorter useful lifespan overall.
Re-charge after it gets light/medium brown. Depending on the size of tank and the water conditions & quality, that could be anywhere from approx. 3 to 6 weeks as an average.
I re-charge mine after 2-3 weeks.

I generally give it a 2 months period. Like most of our planted tanks, the bio load is huge. You can do 3 months. After that, I don't even bother to regenerate anymore. I just use a new portion. A 250ml bottle can last me over 6 months with my 40g high tech tank. Why would I want to go through the hassles and the "dangers" to regenerate them...

Says soak for 24 hours in bleach, then 8 in prime, then 4 more in buffer. Is that what anyone else does or is there a better way to do it?

Thanks
There is no way it needed to be recharged after 2 days. It will start to turn brownish but that doesn't mean you need to recharge it or that it needs to be. It just means its working.

Nice thread that answered many of my questions (just bought some purigen a week ago) thanks!

I have a couple more questions:

Is there an average amount of time to wait between recharges (other than its color, something like once a month rule for carbon?)

What is the life span of purigen? Does it ever reach a state where it is no longer rechargeable?

ime using purigen 24/7 over several years, to me color is still the best indicator of when to re-charge. Do it before it turns very dark brown, whether that takes 3 weeks or 4 weeks, or 6 weeks or more, in your particular tank.

As I mentioned earlier, I re-charge mine about every 3 weeks, and have re-charged many bags up to as many as 12 to 15 times before I get the sense that is has outlived its useful, effective life, then replacing with new.
So a 250 ml jar can & does do me for 4-6 months, using the full jar of beads spread among 4 bags, 2 of which are in use in both of my AC filters, while the other 2 are being re-charged, and then allowed to sit in conditioned water awaiting their next usage.

The evidence of the efficacy of that routine, is that my tank water remains crystal clear all the time.
