DIY Overflow Pipe

[ahho]

Hi All

I've copy the DIY overflow pipe from the member here

This is with the help of my friends workshop. I've tested and happy with flow..

I'm using a 20mm pipe with 50mm outer pipe. Please advice what's the maximum flowrate can this take?

My tank is 48" x 20" 20" and keeping few fish and LPS.

I saw the AqueBee 3000. The pump look small for 3000 flowrate. Is the pump powerful enough for return pipe? Thank you

Hi bro,

Technically speaking 20mm pipe may not handle 3000l/hr of flow.

Based on the below you, after conversion into metric measurement, a 20mm pipe will be able to drain about 1500l/hr.

One of my previous tank with similiar durso pipe, I used Eheim 1048 which have a flow of 600. I never tried to increase to 1500l/hr. But I have tried with a 2000l/hr pump and it definitely cannot handle.

Btw, most reefer with prefer to have 10x the tank volume of flow. Thus for your case, you may need a minimum flow of 3000+l/hr.

Thank you bro Gouldian

I'll try to look for 2000l/hr pump with controllable valve..

Maybe custom make another bigger overflow pipe

Cheers..

Tks for the useful link. I base on my water level. I need 2800l/hr flowrate and 28.44mm drain pipe.

Might need to re-do.. This time will look for transparant pipe..

IMHO transparent pipe will be covered with alage in not time. But I do agree that it look good when new. Have fun!
