Re: Can I put wood in the tank ?

I'm not a chemist, so I'm not sure....

However, I don't believe the tannins affect the fish at all.

Lowering the pH just means the water is more acidic.  However, all acids are
not the same and not all acids kill fish.

A lot of our local rivers are full of dead trees and I swear you can taste
the tannin in them.  It looks as if you are swimming in weak tea.

I refuse to pay LFS prices for pieces of wood and just pick up my own, boil
them for 10 minutes, soak them for a week and then toss them into the tank.
I have often had the tank change colour for a few weeks but have never lost
any fish from it.
