question about trickle filters...

I've recently 'upgraded' my tank to include a trickle filter design.
Basically, two pvc tubes take water in from just below the water level and
carry it down to the sump below. It's then pumped back up to the other side
of the tank. My question is, how do I make the input less noisy? I put fine
netting over top, and that reduced the sound somewhat, but now there's a
higher pitched occasional sucking sound. Any suggestions?
TIA

Try making a custom standpipe overflow as shown at this link:

Here is another good one to try if it fits your application better:

Good luck.

I take it a trickle filter is one that goes down a slope to the bottom and
pumped to the top again?

You may need to adjust the bottom pipe it sounds like its to far out the
water. so just raise the water level of lower the pipe.

TIA - Make sure no air gets pumped in. Air in the pump is often
responsible for such noises.

I've that does not work you may need to take a little aquarium water out, to
just above the line of the pvc tube to try and stop the noise. I tried it
with a system they had at a shop. I put my thumb over the tube to stop water
going down and let go after 5 seconds and it made a noise as the water level
was returning to normal and then it stopped.
