RE: Moving....
As far as I understand it, there are numerous strains of the beneficial
bacteria with most of them capable of living efficiently around the neutral
pH mark. However, the quantities/efficiency begins to drop off about 6.2 and
will fizzle out at around 5, but there are some still around. So on this
count it is probably justifiable to maintain filters and sponges on the
basis that something is better than nothing.
I remember this from a paper somewhere, but I know not where now....

Bio filters are not functional at a pH of 5.0 are they?
