Hofer Gurgle Buster

[phar]

Hi all,
I've moved my tank upstairs into my living room. I have a 90 gallon drilled with one drain and one return. The problem is it gurgles like crazy and may drive me mental.
I was doing some research and found this:

Has anyone tried this? Does it work? Any suggestions on trying to make the drain as nearly silent as possible. The water gurgles going in and coming out. I've got a reverse durso drain on the bottom but it doesn't work very well for reducing noise. Any other suggestions?
Thanks,
Patrick

I did the Hofer on my 155 Bow as it had very small overflow boxes. Was very easy to build, worked great & was very quite.

I have a hoffer running on my tank. Used 1 1/4 pipe though....
It works really well.And like Griz says, its cheap to make and an easy install in a tight OF
