Powerheads with venturi/air hose connection

mortician · Jul 3, 2023

Hello,

I am having a hard time figuring out what brand powerheads have a venturi/air hose connection. I am about to setup a CPR aquatics overflow and have heard overtime the aqua lifters fail and would like to add a powerhead with a venturi as a preventative measure. I was looking at the hydor koralia's but looking at all the images and descriptions it seems they do not have one.

Thank you!

None that I can think of offhand. Anyone else?

HOB U-tube mod

I am modifying hang on back U-tubes to hook them up to Venturi powerheads. Idea is that will suck any air out of the top and retain the siphon (I miss aqualifters) I have it working fine but wondering if there is anything I can do to improve the suction coming from the u-tube? As it stands now...

The current Marineland maxi jet has the option. Btw they redesigned the aqualifter. I am not sure if it’s better or not. Remember aqualifters are diaphragm pumps. They need to be serviced or replaced every so often. Toms even sold replacement parts so you can diy. I am not sure if the current one has parts out for it.

Interesting I didn't know they redesigned the aqua lifter, I thought the company went out business or something. I will have to look that up!
