Thank you for your replies. My overflow box hangs on the side of the tank. I am getting a loud trickling sound where the water enters the tubing that takes the water down to the sump. My equipment came with a round porus sponge that I have positioned around the opening. That does not seem to do the trick as far as mimimizing the noise. The local fish store told me to insert a brush into the hole..that way the water can still enter the tubing. I just held the brush in place and it did seem to stop the noise, but I am worried about the brush being pulled down into the tubing. There has to be some type of adjustment I can make with the sponge..it seemed to do better temporarily when I pushed the sponge down, but the problem continues as I write..sorry don't know the name of the manufacturer of my equip. offhand,,I will look it up and post it when I know. In the meantime, any suggestions would be appreciated..it is driving me a bit nuts!.(
