say it ain't so! could my driftwood be buffering my pH? after
placing a handful of gravel in some R.O. water, the pH went to 7.6,
not even co2 could lower it.
i am planning to replace the gravel with a substrate that will not
buffer my pH basic. but before I tear my aquarium down, i decided to
test everything in the aquarium (ie, gravel, rocks, & driftwood).
the various rocks I have didn't cause pure R.O. water to change it's
pH, but the driftwood did. it went right to 7.4. could this be? i
got the idea that a decaying piece of driftwood would produce more
acidic conditions. what up?
