I know that driftwood will lower pH, how much will it lower it? Are we talking whole numbers or fractions?
Depends on the driftwood but IMHO 1 ix possible.


Also if I add some Limestone rocks to the tank will this help balance out the driftwood?
vtg: yes but you used the plural form.

Please think in terms of just one larger limestone rock.

I presume that you are thinking of aggregate which can be obtained from a local roadway construction site: the aggregates in the base material are not of sufficient size but the Contractor will have some fist sized stones (they will probably refer to them as cobs) stockpiled on the project site somewhere.

This one limestone rock will provide "buffering on demand" (or at least an Edwards Plateau limestone rock).

jones57742: Thanks for your help! I was planning to get a few and create a cave, but I will change my plans. I have no idea where I will buy the stone, I need to do a search to see what is in my area.
vtg: In my previous post I started to delve into surface areas with respect to volumes with specific calculations but thought about the "fallout comments razing me".

I now believe that some expression of the concept would be appropriate:
A = 4" spherical stone
B = four 2" stones to consume the approximate space of one 4" stone

The surface area of A is equal to B but the volume of A is twice that of B.

IMHO this ratio is important with respect to the following concept and the preservation of the stone in near original form.

IMHO for harder limestone (ie. many Edwards Plateau Formations) the effective mechanism is not the stone dissolving in the water but the reduction of acid in the water by direct contact with stone.

If you are "gluing" these stones together the increase in the volume/surface area ratio may be (I just do not know) that this cave might work for you for an extended period.


This is sort of another question, but has anyone used "found" driftwood in there tanks here? My brother always did and he never had a problem, I was thinking of making a trip to a river near where I live...
vtg: I have never tried this much but many folks have reported good luck.

You might consider boiling the wood in a mild chlorine solution for several hours and dechlorinating prior to placing in your tank.
