+Eckreef Posted August 13, 2009 Share Posted August 13, 2009 Still researching ideas for overflows. I have been playing around with a durso on my 40g breeder but still am not completely happy with it. Options so far are the Durso standpipe Stockman standpipe Hoffman Gurgle buster and I recently discovered a silent and fail-safe overflow system Does anyone have a silent overflow? Care to share your secret? I am intrigued by the silent and fail safe system...anyone have any experience with this? Thanks! Quote Link to comment Share on other sites More sharing options...
+dapettit Posted August 13, 2009 Share Posted August 13, 2009 When I first set up my durso it sound like a toilet flushing. I gradually enlarged the hole in the top until it stopped making noise. Dave- Quote Link to comment Share on other sites More sharing options...
pbnj Posted August 13, 2009 Share Posted August 13, 2009 Drilled or non-drilled tank? Quote Link to comment Share on other sites More sharing options...
+Eckreef Posted August 13, 2009 Author Share Posted August 13, 2009 Current tank is bottom drilled (x2 1") but I am considering starting over with a new tank and selling old one depending on what the best options are. Quote Link to comment Share on other sites More sharing options...
rosslonghorns Posted August 13, 2009 Share Posted August 13, 2009 I just used the standard durso on all the tanks I've owned. I would say mine is relatively silent. Like stated above I had to enlarge the hole. I also believe it had to do with my return pump and volume. In some of my initial tank setups, I had a substantial amount of flow through the sump, thus the overflow had to keep up with this. More flow, the louder it was. After reading a few articles on Melevs site, I went with the recommended ~3-5x flow through the sump. As a result of that, the overflow wasn't as loud as the volume was minimal. What return pump are you using on your 40 gallon? Quote Link to comment Share on other sites More sharing options...
Robb in Austin Posted August 13, 2009 Share Posted August 13, 2009 I'll be setting up the silent/failsafe system in the next few weeks. I'll let you know how it works out. Quote Link to comment Share on other sites More sharing options...
