With all due respect, I would assume that Amano knows what he is talking
about when it comes to planted tanks. he recommends the use of carbon on the initial stages of the life of the tank, 1 to 3 months, and on some of his tanks he runs carbon perpetually. And I personally have shrimp tanks that are planted. It comes down to preference, I love purigen and will continue to use it, if its just biological filtration, or no filtration that works for you that is great, but no remedial reading is needed by one here, it's just a different school of throught.

No single one thing is going to be the silver bullet for anything.

Actually, in one case it was the silver bullet. I had a tank that got no algae through the entire live of it except green water. I attribute this to it being by a window. I had a portable UV for awhile. Then I tried Purigen, thinking it wouldn't do anything. It got rid of the green water really fast. I never got green water again but sometimes I would notice that it had green spots.

That is an odd thing though. I have never had a tank that balanced get green water.

I have one pouch that is almost 5 years old and still will be pure white after bleaching. As said, I only run it on nano's now so the pouches aren't excessively expensive, fit in most filters, and go forever.
Exactly my point :P

You're right. Free and planted tank hobby don't go well together. But that's why its worthwhile to some to pull to jump on it whenever and wherever we can

The only case here is really financial-related. Plants do what purigen does but perhaps not to the same degree.

People have had success with and without Purigen. There's no other harm to using Purigen other than to your wallet.

dprais1 Anybody care to clarify these statements for me....

1. Purigen removes organics from the water.
2. The breakdown of organics cause the toxins
3. Therefore purigen is not a chemical filter but a really good mechanical filter.

4. It works so well because it is sticky (like a really well aged sponge filter gets when it has lots of bio bacteria in it). It is just a lot stickier than even a good aged sponge type filter)

...or I completely off my rocker!!

STS_1OO I concur that 50% WC, especially with ferts, is nothing drastic so as long as we're talking about fish here. That being said, WC are not necessary unless you're ferting regularly.

I can't speak to purigen but I do know that may people opted for a cheaper solution in Polyfill - the non-chemically treated pillow stuffing...stuff. I've had it in my Eheim 2215 for two years now.

Not only does it saturate first, its easy to throw out and refill and very cheap.

Polyfill keeps my tank crystal clear. I'm also not big on chemical filtration for a planted tank.

talontsiawd I use Purigen in nanos, nothing in tanks larger than 10 gallons. My only reason for that is Purigen doesn't last very long in my larger canisters before it's "saturated" and I don't clean accordingly, making it kind of useless.

I have also used a UV over the years. I rarely keep it on. It's great to plug in for a day for super clear water when you are having people over. I likely wouldn't buy another.

At this point, I could care less about chemical filtration, I just use it because I already have it.

herns I don't use chemical. Just eheim rings, ehfi lab & filter blue & white pads.

Just wanted to see what everyone else was using.

FWIW I have two Eheim 2217 can's on my 75G tank.

Thanks,
