I think Dave was questioning the policy of using a pH controller, not the
technical details. His question is (and it's a good one); your fish
don't need it, your plants don't need it, so why do you need it?
Two possible reasons come to mind. You can get it to help prevent
end-of-tank dumps. Or you could get it to keep CO2 from getting too high
at night. I suppose you could also get one to amuse yourself or to
relieve yourself of some heavy and otherwise useless cash.
