Best carbon to remove tannins

  • We are currently upgrading MFK. thanks! -neo
Not sure if tannins are even your issue. My water is almost tea colored when I do wc into a white bucket and It definitely doesnt effect clarity. I add blackwater extract since my dw doesnt release much anymore and iirc the "blackwater" parts of the amazon are the cleanest clearest parts.

just wouldnt want to see you try to fight the wrong battle for water clarity since I find most clarity issues are either bacteria or algae blooms or lack of mech filtration

I have a few larger pieces of driftwood that I inserted into the tank about 5 weeks ago. I'm not sure how long tannins come out of the wood for but I was assuming this is what was giving my water that tea brown tint. I added some cheap petco carbon to my fx6 filter and it cleared it up a little. I figured a better carbon might finish te job, but this purigen stuff seems to be something I want to try. Do you guys run purigen regularly or just when you need to clear up your water?

Tannins come out for a long time sometimes years and can be toxic.

That's why I'm pre soaking the wood I'm using now. So I don't have to deal with it to bad.

The guy with the 770 G tank soaked his in his hot tub for months in a regular hot tub mix ( chlorinated) and it still leached after it hit the tank.
( 1st page aldiaz33)

My piece is roughly 1/2 that size, I'm soaking it until the weather freezes or it sinks on it's own with the slate I put on it today.
I might even bring into the basement for the winter. I don't care to much about it leeching more sinking. I might screw another piece of blue stone to the bottom of it.
As far as the purigen? From what I have read you run it 24/7 in your filter. I just wasn't aware it worked better on tannins then charcoal/carbon for removing the leather water look.

I run Purigen 247. Recharge monthly or bi monthly

Wow if tannins can leak for years I may just take my wood out so I eliminate the problem

You will never notice it with filtration once the piece is seasoned.
you would need to test the water for them ( the acid) down to the PPM. and like anything else it is finite so the longer it's in the less you have.
It's the main reason so many people me included soak the snot out of it before we toss it in our tanks.
That and to get it to not be a cork.

One reason flooded forests and stump ponds have black/tea water, organic filtration not the particle removers we all use on our tanks.
Tannins go down fast you would probably have to shut your filtration down and stop water changes for a few days to see the water get colored up again.

Only certain woods are acid toxic like birch and such.
Somewhere on the site I replied to another guy asking about them with a lot of scientific links/sheets right down to the MSDS on the acid/wood he was using.

I was just glad to find out purigen does a better job then carbon.
I don't use carbon in any of my filters unless I have a real need for it. Removing tannins is one.
I've been on the fence for a long time about purigen I'm pretty much sold now on it.

Well at least enough to give it a try.
