After trying to fit durso stand pipes into my overflow unsuccessfully I came up with this simple solution. Its two 6" sticks of 1" pvc pipe with 1/4" holes drilled into it below the water line. Caps with 1/16" holes drilled above the water line to allow air in. I started out with 3 holes below the water line and added 1 at a time untill the water was at the level I wanted, 6 holes in each pipe total for my setup. It is now totally silent.
Can you post picture? I thing details are very important and helpful.
its a little hard to see in the pic but the idea is for the water to enter the drain pipes below the surface through the 1/4" holes. this way the water is not falling and making noise. i kept the water line high enough so that it dosent have to fall at all. Im using a mag drive 9.5 pump so there's 700gph or so flowing through my over flow that is now wisper quiet.
Better keep on top of that.. little slime, food or algae covers one or two of the holes and you my friend have yourself a flood.
it has been running for around 3 months now with no problems yet. i thought the same thing but im guessing the water is flowing fast enough to keep the drain holes clean? also if the holes do get a little stopped up the water level will rise in the overflow box and cover the air holes in the caps. this will make loud gurgling noises kind of a alarm to let me know something is wrong. hasnt happend yet though
been in the hobby 15 years to know this setup is a huge mistake... don't take this the wrong way but others here are trying to tell you the sme thing... weve been there. Now if you truly want a quiet overflow and yet safe against floods... check out Beananimal's desing on Reef Central. its the best system that I have seen to date. It implements full siphon three pipe system. I built it on my custom setup and its amazing what happens when you eliminate air from a water line... it makes absolutly no sound at all and also you benefit from larger flow and turnover rate (if thats what you are looking for). in other words the same 1" pipe as you are using at full siphon will handle 10x the water volume as in your example trying to push air and water through the same diameter... goo luck.Originally Posted by weatherby68ss

yup thats the one I was talking about... Its the best overflow system we have in the hobby. just do a you tube search and you'll see its true power and grace.

I had something similar about 20 years ago, but I left the cap off and had a sponge over the pipe so as to filter the water as it drained. If it backed up the water would just run over the top to the sump, but this never happend. A piece of airline tube down the pipe reduced most of the noise. This worked fine for years till I closed the tank down.
+1 on disaster waiting to happen.
