Somebody have some idea about this product.

Well it sounds like it wouldn't be very good for a planted tank, given that it takes out nitrates.

Apparently it only takes out the organically produced nitrates, not the stuff we dose.

I am not too sure about the stuff, but i have friends who swear by it.

I did get a small bottle myself to test out. I don't really hold much hope of it doing anything, but hey a little experimentation... a little more knowledge of what is crap and what is not eh?

There is really no need to use it in a planted tank. But it works very well in saltwater/reef tanks.

Once again, lots of misinformation being spread.

I use it in my planted tank with excellent results.

Purigen absorbs dissolved organics with specific properties. This is the kind of stuff that can make water cloudy and/or smelly, create foam, or have a film on the surface (among other things).

Purigen works by using physicochemical forces to attract atomic particles.

Think magnets - the positive charged side of one magnet attracts the negative charged side of the other, but pushes away the positive charged side of the other.

For example, Iron is charged positive, and if Purigen is also charged positive, it will not absorb any Iron.

Purigen is engineered using a proprietary process so that its physicochemical forces attract and keep only those particles with specific types of electric charges.

Its effect on the products typically dosed to a planted tank is minimal and of no consequence.

If it attracts negative particles will this remove hydroxyl ions from the water and raise PH?
To state a different way, did you observe any change in PH when using the purigen?

My understanding is it absorbs particles with specific types of charges.

I have a pH meter in my tank running all the time. Purigen has zero effect on pH.

I don't think I've ever seen clearer water than water filtered through Purigen. It almost looks like the tank is empty and everything inside is floating in zero gravity.

Purigen was designed to attact organic nitrogen particles. I use it in my planted tank and am very happy with it. One nice benefit of this product is the micropores work similar to a diatom filter and really polish the water giving unmatched clarity in my experience.

I bought the product because it was recomended for removing tannins from wood. I need to get some very fine filter bags before I can use it, the material is tiny (less than 1 mm).

Anyway here's pictures of what it says on the box, can't wait to see it in action.

I was looking to do this a while back, but never got around to ordering it. I was thinking about keeping it around for occassional tank 'clean-ups', but would love to hear more how others use it.
