Was going thru reefcentral.com pages and i came across someone building a standpipe and called it a Hofer Gurgle Buster. They claimed it was much more efficient then the method that i use (durso). Funny thing is, i've never seen this design before. Was curious if anyone here has tried it or heard/seen of it.
