Hofer gurgle buster
 

Has anyone here tried this form of overflow piping?
It appears to be a decent design and I have read a few good things on some other forums.
What do you think?

sounds like a well built unit worth a try!!!

I think I will give it a go. Hey if it doesnt work, i will just pull it out and make a durso or stockman.

I am using it on my 50 gal FO tank. The overflow won't fit a Durso and the Stockman was always noisy. All I had to do was some minor mods to turn the Stockman into the Hofer. It seems to be working quite well, it does what its claimed to do. I've had it in there for several months now. Nice thing is, you can try it and easily switch back to the Stockman set up if you don't like it.
