Jmvanness Posted January 29, 2015 Share Posted January 29, 2015 Set up a new tank. Did the little pvc hook thing.. tried adding tubing... still loud. Any suggestions? 1 Quote Link to comment Share on other sites More sharing options...
Wryknow Posted January 29, 2015 Share Posted January 29, 2015 If it's a standard durso stiyle then there are several things that you can do to quiet it. 1) If the water flow into the sump is surging fast/slow/fast/slow then you need to let some air into the top of the durso pipe. I use a small drill bit, add a small hole, see if it stops, it is doesn't add another small hole, repeat until the surging stops. 2) You can reduce the splashing noise in the sump by adding a 45 degree elbow a couple of inches above the sump water level and then running some flex tubing to the top of the water level so that the water slows down instead of crashing directly into the sump. 3) Durso pipe should be at least 1 size larger than the bulk head. If you have a 1" hole then you should use 1.25" pipe 1 Quote Link to comment Share on other sites More sharing options...

MantaFan Posted January 30, 2015 Share Posted January 30, 2015 I gave up on trying to get a durso to be quiet... You'll never get rid of the running water sound unless you significantly decrease the flow. I went with the herbie method for that reason (http://gmacreef.com)... My tank is completely silent :-) Sent from my iPhone using Tapatalk Quote Link to comment Share on other sites More sharing options...
Jmvanness Posted January 30, 2015 Author Share Posted January 30, 2015 So it's the sound at the durso not the sump that is bothering me. I tried to increase the size to 1.25" but can't get it to fit. I'm now trying to get a herbie set up. Quote Link to comment Share on other sites More sharing options...
Jimbo662 Posted January 30, 2015 Share Posted January 30, 2015 did raising the water level not work? Quote Link to comment Share on other sites More sharing options...
Jmvanness Posted January 30, 2015 Author Share Posted January 30, 2015 I got the herbie working! Now all i hear is the splash from my waves... thanks Manta! @Jimbo, yes i raised the water level, but it was getting rid of the air intake that made the most difference. It is literally silent now. 2 Quote Link to comment Share on other sites More sharing options...
