HOW TO: DIY Overflow Silencer 

Thanks! :)

You're welcome Le jones :)

No, the water will only flow into the sump until it is down to the bottom of those drilled holes, then stop, so the overflow box will remain full to the bottom of the holes during a pump/power failure

it wont cause flooding because there will be no debris since the overflowbox will now also act as a settlement chamber. the only reason the water level is higher is because he placed the holes on top

Thought so.

Yes, dalawa butas ng bottom glass. Overflow and return pipe.

yes, it's not fixed.

@@charles2low2drag how is it held down? Is there a pipe sticking up out of the overflow at the bottom?

@@JohnBullas Yes, that's correct. I've added a long pvc but did not glued it from the bottom union pipe so it's removable. because of the water pressure it holds itself and no risk as well as this is just to shorten the length of the water falling from the top.

size 25mm yung return, size 50mm yung overflow 25mm - 3/4" 50mm - 1 1/2"

Charles Apdua boss my tank is 4x2x2.. plan ko sana pagawan ng overflow, should i use the pipe sizes u used o pwedi din ang 1inch overflow then 1/2 return? I’ll be using rio 14hf sa return. Thanks

Ordinary lang po.. size 1/2" :)

yes, it should be a little bigger than your pipe around 5-10mm bigger.

Nope it wont.. if it did, you just need to drill more holes

Yeah right.. that's what a stuborn person will do but if you're passionate about your hobby you'll do better than that.

Charles Apdua stubborn?

A spunge would also collect detritus that can cause other problems, and would need more maintenance.

Matt Prinsloo since when collecting shit is something bad? Yes it will collect more and it will grow useful bacteria for the tank and yes more maintenance...
