How much tanin is too much?

I have this really large piece of wood (mopani) ,too large to fit in any container to boil or to fully soak.
If I were to soak it partially for a couple of days ,and then drop it in the tank ,I imagine the water would quickly turn brown.Not a big problem for me ,aesthetic wise ,not a problem about light penetration either ,as the tank is only 10 inch high.
I usually perform a weekly water change in the tank ,could the ph drop too low in 6-7 days because of the tea?

I also read that tanins are somewhat benefic to the fish ,but ,can they cause problems if the water is too"brown"?

Can't come to work today ,Boss......I've got Bolbitis...

Get purigen. I rinsed my mopani and threw it in, water was tinged yellow for a month, but cleaning and replacing the purigen often took care of it. now it's crystal clear.

I have a piece of wood that is about 16" long. The only thing I could find big enough to boil it would have cost at least $40. I have no clue what made me think of it, but the words 'thrift' and 'store' entered my mind. The first one I went to, I spent $5 and got a stainless steel 18" oval roasting pan with lid. It was old and used, but the wood fit in it. Even though I don't think they are intended for the stove top, I had it sitting on both a front and back burners and was able to boil away to my hearts content.

And it was a good thing it only cost $5 because I seriously doubt the ring of sludge that formed in it is ever going to come off it.

The tank is about 30 inches long ,the wood is like 22-25 inch long. At its widest points ,it would touch the front and back glass - tank is only 8 inches wide ,a weird-shape custom made tank ,to place on a narrow fireplace.
Anyway ,here is a pic.....the wood looks great and I don't want to give it up ,no matter the color of the water....

Won't that take up all the nutrients from the water?I only have Crypts and some Najas Guadelupensis ,enriched substrate.

nothing wrong with a ton a tanins in the water, some dw will leech tanins in the water forever. look up blackwater fish tanks, some people actually like the look and as you have stated its actually beneficial for most fish.

Hello sleep...

Boiling will weaken the wood fibers and it's doubtful there's anything on it to harm the tank inhabitants. The tannic acid leached into the water is minimal and may drop the pH marginally. Nothing that most aquarium fish can't handle. Keep up on the water changes, that's the best way to remove the tannins. Tanks are healthiest if you can work up to changing out half the water weekly. I change out more than that, to keep most of the dissolved wastes out of the water, but not many water keepers are interested in this routine.

Your Tap Water

Hello again sleep...

The pH is fine. Most, if not all fish you get at the store will easily adapt to most public water supplies. A steady pH between 6 and even 8.5 is fine for most fish.

Don't fret over the chemistry end of things. Things like this are unimportant. Unless your plan is to keep and breed rare fish, all you need to do is treat the tap water to remove the chlorine and chloramine the public water people put into the water to make it safe to drink. Seachem's "Safe" is likely the best product available.

I love peacock gudgeons, and tannins. I've put 3 different pieces of Mopani wood in three different tanks. All of them leached tannins for maybe a month. I always do weekly 50% water changes and all the tannins are now gone. The marginal drop in ph from the wood is different from, say, a quick change from your source water. That's a cool piece of wood!
