Hi- I have a question for you guys about air pumps. I have a noisy profile 1000 in my room which I shut off at nite to gain a good nite's rest. I have it running a 10 gallon tank equipped with an undergravel filter. My question is does it harm the PH or the filter bed at all by shutting it off at nite?
