I intend to put stones or pebbles in my wildlife pond which won't have any
fish apart from maybe the odd stickleback. My preferred pebbles are
limestone but I have seen a warning against using limestone pebbles
because
they can change the ph. Should I take this warning seriously?
thanks, Davy
=========================
They don't change the PH of my ponds and tanks. In fact I believe they keep
the PH from dropping by acting as a buffer.
