You may want to boil it first to reduce tannins which will yellow your water, but:

What could you do if you didn't want to put wood in the tank?

 

[SimonL]

I'd use a mix of RO and tap water in that case.

Just to point out... Tannins is actually Tannic Acid... and it's the tannic acid that makes the water more acid, or lowers the PH...

So the more Tannins the wood leaches the more effect it will have on PH, the less it leaches the less effect it will have... Though I should also add, just because your water isn't turning tea colored, doesn't mean your wood isn't leaching any tannic acid at all...


Peat will also lower PH, though it will also tea color the water...



It is much easier to Buffer water Up than down...

is there a specific reason for wanting the lower ph?

IME you're better off not messing with the pH in such a case.
