hey,
in doing a search it looks like a lot of people are suggesting putting airline tubing down the pipes to reduce noise. In the reeftanks forum it was suggested that broncofish had another idea--i couldn't turn that up in any searches, but I'd love to hear it!

Its a durso standpipe. Do a search for Durso youll get lots of results.
It solves 2 noise problems,
1. Waterfall sound as it raises the water level
2. Toilet flushing sound as the water intake is below water.
Hope that helps
