I just picked up a 100ml bag of the stuff to use between a 30g and 72g as needed.

Who has experience with it? Sounds easy to regenerate with bleach, Prime...do I need neutral regulator/acid buffer/discus buffer in the regeneration process?
 
I've been using purigen for about a year. I love it.

It turns dark orange when it's ready to be cleaned. I soak it for a couple of days in a bleach water solution mixed half and half. I then rinse it and soak for another day. Add prime, test ph, and let dry. I'm sure that's excessive, but I worry about killing my fish.

You can use acid buffer to help neutralize the bleach if you keep it on hand.
 
Check Seachem's website for the whole regen process. I use it in almost all of my fifty odd tanks and love it. Vequalsir you can actually let it go until it's almost black before regenerating. According to Seachem they get about 10 cycles out of it before it refuses further regeneration.

The only downside is the cost. Pricey goin' in but given the service life I've been pleased. I have it in HOT's, HOB's, sumps, phosban reactors and canisters and it's been good in every application. Word of warning though. If you buy the bulk powder you really have to use their bags, which are also top notch but expensive, 'cuz the stuff is fine enough to fall right through everything else that I've tried. Also because it's so fine I guess it's also like tryin' to restuff a bean bag chair. Even the tiniest bit of static charge has this stuff sticking to everything except where you want it to go. The term herding cats comes to mind. Stick with the 100 ml bags.

They also make a product called Hypersorb that looks to do about the same thing but I'm told that the Purigen is a 2nd gen. product that also picks up heavy metals for about the same cost.

Their customer service is also a great resource for water chemistry questions...as long as you're using their products of course. Dey ain't cheap but I've gotten my best prices on their stuff from Ken's Fish. Anything that he doesn't have he can get for you.

I don't think Seachem says the use of buffer is necessary (this is new advice):

The directions on the box include the buffer, but not sure why...This was what caught my attention...

Love SeaChem, may seem pricey but compared to carbon and other chemical filtration it's not bad...especially when you can regenerate it.

My plan is to run Purigen in a canister or power filter with the 100ml bag. I can rotate it on regular intervals and keep 2 tanks spotless with one bag. SeaChem makes awesome stuff, love Prime and I cycled with fish using Stability, and I expect Purigen to be a real SPONGE for the nasties in the tanks.
One will be a cichlid tank that in time will be over stocked, so the sump will need help..

Never use it..though I could see it as an emergency device...
 
I use Purigen in my SW tank. I have six 100 ml bags floating in a HOB filter. I regenerate them every 4-5 months or as needed.
 
I was initially concerned with the effect that it would have relative to cycling. If it extracts ammonia, nitrates and such what would happen if I pulled it out for a few days to regenerate? Would the tank begin cycling? I've never tested the question because I always maintain a few unused spares to replace the ones that might be temporarily removed, but it still seemed a possibility for someone who might buy just one to check it out.

Rumor has it that there are people who actually have the inner fortitude to own but a single tank...but I'm pretty sure that they're all doctors and they just keep it in their waiting room.

You're thinking plastic surgeons...they pay someone to do it so they have more time to screw the hired help...:Angel:
