Fish Crazy
i have an interpet av4 air pump (double air outlet), attached to this inside the tank are 2x 12" airstones on tubing, i had a long tube which i manually put holes in thinkin the holes werent big enough or not enought of the so bought proper air stones. The noise is terrible! any ideas or is it a dodgy air pump? its just hummmmming and i read they were supposed to be quiet!
