The quest for ever purer water, I'm curious about the Seachem Purigen product (not to mention RO water, diatom/micron filtration, UV sterilization...).

Has anybody used Purigen? Opinions?

I use Purigen in all of my tanks......... Mine are fully planted also. Incredibly clear tanks with fish looking almost suspended in the water, it is that clear! I am a huge fan of the stuff. I don't use RO water, but I think that as far as clearing water, the Purigen is as or more effective that a diatom filter, which I own, but have no use for since the Purigen.

Cheers,

Melanie - thanks for the feedback. I was begging to think no one had tried it. My water has always been very clear - so the filtration is good, but it's like love, health and wealth - you can never have too much.
And by too much, I don't mean a zillion gph, but continuously fine filtration.
I think I'll order some and give it a try.

(I had a diatom filter in the olden days that I'd hook up every once and a while across many tanks and I really liked the way it polished the water (although the flow was too great for some tanks). Just not sure I want to go down that road.)

Thanks again

I did a ton of research online and the general consensus was that you just couldn't beat Purigen for water clarity...I think one person used the term 'uber clear' water. Yes, it is that clear. Some say that it removes ferts, Seachem says it does not. I use Seachem ferts & products and regenerate the Purigen all of the time. I am not a chemist, nor do I have a science background. I am just a woman who loves to have a house full of display tanks that have spawning fish. Obviously happy fish. Takes care of the empty nest syndrome. My planted tanks are gorgeous and thriving. I need to get in there with a weed whacker almost weekly. Give away an incredible amount of clippings & plants to folks who would like to try planted tanks. No algae. None.... Stable tanks. Maybe it is not all Purigen, but it sure can be attributed in part to the Purigen, IMO.

I would suggest to get a test kit that measures chlorine levels when you are done regenerating / rinsing Purigen just so that you know for sure that the bleach is absolutely gone. I am a worry wart, so that is something extra that I do. Don't trust my nose to detect a minute amount of bleach.

Cheers.....

Melanie

Melanie,

No worries on the regeneration as I would treat with Prime as recommended.

Had to look this up as I was unfamiliar. Interesting... nice to have an option that is not an additive like the Clarity I used. So I take it I use in in place of the top filter pad/sponge of my external canister?

Please report back when you start to use it. I think I might go for it, too.

Purigen is an adsorbent polymer resin about the size of small gravel. It must be contained in a fine mesh bag. They sell 100ml in a bag, but they also sell it in a (liter) jar and you supply the bag.
Seachem markets 'The Bag' but it's a bit pricey @ $9.

Purigen can be placed anywhere in a filter, but I would place it after the initial mechanical (typically sponge) filter and before the final sponge or floss 'polish'. Put it where (or along with) where you would put activated carbon if you used carbon.

Okay, I placed an order for Purigen and Seachem's Neutral Regulator (as the chlorine used to regenerate the Purigen tends to dramatically alter the pH, which could subsequently affect the tank water).
Thinking ahead, I ordered two 100ml Purigen packs (mesh bag included) so I can have one in the filter while the other is regenerating.
I'll make a point to evaluate and come back with a follow-up.

The Purigen arrived today. 1 bag (100ml) treats 100g.
The 100ml bag is smaller than I envisioned - the purigen is also a very small particle size.

I serviced the (AquaClear 70) filter, Bottom up, it is now setup with a scotch-brite type pad, 2 AC70 sponges, a filter pad, the Purigen bag and filter floss for a final polish. (I have Matrix bio-media in my other filter).

I'll report any observations regarding water quality and Purigen loading (according to documentation, as it collects organics, the color should begin to change for blonde/off-white to brown/black).
