Hi All,
This is my madien post.
Have a old 3 feet tank. Drilled the tank to take a 20mm PVC pipe as overflow. There is no box surrounding this overflow pipe and the pipe is just sticking out on the left hand side of the tank.
When I pump the water from my sump, the overflow is very noisy, how to silence it. ? I have tried stcking a PVC hose in to the overflow pipe as suggested by others but with no improvement.
Please help and thanks in advance.
