Noisy internal overflow

[abe77901]

Just finished installing my new 100. It has a corner overflow and everything is working wonderfully. 1 problem, noisy overflow...water flows through the slots and hit the water kinda noisy, how can I stop this? Any help appreciated.

The noise is coming from the water dropping inside the overflow? Or is it coming from the overflow into the pipe? How low is the water inside the overflow?

its coming from the water splashing down the overflow into the water below.

I had the same problem until I installed one of these: http://www.dursostandpipes.com/
you can buy it from aquatek, or you can build it your self for about $10-$15 from home depot or lowes

If you look at the picture in the link above is your water level in the overflow lower?

If you still have some splash you can fill the overflow with rubble.

my water level is about half of what the pic is above in the link

I'd build the durso and put rubble in. Rubble will house a bunch of pods.

what kind of "rubble" will it not then raise nitrates???

[Tim Marvin]

No, live rock rubble and keep it submerged. If you install the durso it will bring the water up a couple inches from the top, and all the rubble in the overflow will house the tiny little critters that would be eaten in the main tank. These little critters will end up being pumped into the main tank, but the population is safe from being totally wiped out in the rubble. This is one way to keep a healthy pod population in your main system.

I added some macro algae in mine. The only modification I made to the durso was that I added a 6" peice of PVC to the down side of the elbow and drilled a bunch of holls in that piece to make it a mesh. This way I can make sure that no large object can completly slop the flow.
