How long to get tannins out of wood?


I bought a nice piece of malaysian driftwood from a lps for $2 to fit into my 2.5g tank. Here is a picture of it:


Here is how big it is in my 2.5g tank:


Here is it soaking in some hot water:


I thought the piece of wood was small but it appears to be big when I brought it home. Either way, it fits in the tank, but not in my tiny pot. So how long should I be soaking it before using it? How long before it sinks?

Boil it until the water looks like tea. Pour it off and refill and boil it again. Do this until the amber color stops showing up. You will still get some leaching into the tank, but it will go away a bit quicker.

It doesn't fit in any pot of mine. So boiling it in a pot of water is not an option. I am guessing I have about 1-2 weeks before I can set a tank up anyways.

Soak the sucker in a 5-gallon bucket and just continuously change the water. It's a lot slower (months) than boiling and by the time that you're ready to set the tank up, it'll still leach tanins.

I had a piece leach for approx 2 months and the yellowish color was annoying at first but I got used to it. However, mine wasn't as red as yours so I;m wondering whether you'll get a bright red color.

It looks really red because it is wet I think, but the piece was kinda red anyways. I tried boiling one side of it in my pot, but when I tried to flip it over to boil the other side, it didn't fit....lol So I boiled one side for 1 hour and looks like I got brown soup. But at least the log sinks now. So I will just boil that one end every now between soaks of hot water that I change many times a day. Water is still yellow...but I can live with that, maybe.

Try going to a thrift store and see if you can find an old stockpot. They should be really cheap and some day you may want to boil a turkey carcass for soup. No kitchen should be without one!

That looks more like Mopani wood than Malaysian driftwood. You might have some issues with tannins, but it shouldn't be as bad as a piece of Malaysian driftwood.

If you do have an issue with tannins boiling and soaking is the only way I know how to reduce tannins.

I got it from a pile of small Malaysian driftwood chunks at the store. Will there be a problem using Mopani wood? Basically, is it okay used completely submerged? Or does it have a tendecy to fungus up?

No problem if it is Mopani!

You might get some fungus on it, but that is not because it is Mopani wood. Fungus can occur on any type of wood.

For $2.00 I wouldn't care how long I had to soak it!!. You can buy lots of that stuff and sell it for a profit at those prices. Nice wood!!

I was told at my aquarium center to put aquarium salt in with the soaking process. That it brings more of the tanins out.

I don't think putting salt in will really do anything..

i find boiling the most effective of removing bacteria/tannin/leeching/purging driftwoods and FW rocks/stones amongst the other methods. i would take the suggestion of mori and dash to a nearby thriftstore

boil it and keep on changing the water until it boils out with a clear water !

I wonder if salt would slow the growth of mold and mosquito larvae in a no-boil soak situtation. Oh yeah...you're going to change the water often. I'd forget and get nasty stuff growing...
