overflow

[jlena01545]

I just set up an old 90 gallon tank someone gave me, it has a corner overflow and all I get is drain noise, am I missing something?

What is the flow rate of the return pump ?

Its a syncra 4.0 I think 600 gph

I have a 90gal with corner overflow as well. This is what I did. Drill holes in the top of the drain pipe. Use a small drill and drill a hole...listen if not happy drill another small hole until the noise stops. Also make a cover for the top of the overflo. I used a piece of black acrylic.

Thanks, I'm going to try that

If that doesn't work. I think the Syncra 4 is closer to 900+ gph. If you have one of the 90g tanks with the megaflow, I think the flow on them is closer to 600 gph. Maybe try dialing your return back a little bit.

I’m running a Jebao DC8000 return pump. I have it running at 100%. My tank and dump has No problem handling the flow 2113.74gph

Fair enough

Thanks for your help

Google a Herbie drain set up which works wonders if you have 2 bulkheads in the overflow. Typically one was used for a return pipe but you can just plumb that over the side of the tank which is well worth the extra work in order to get a much quieter tank...
