hobie livewell upgrades

I came across this clip on YouTube.

I went a head and bought a flow rite qwik lock power stream aerator, thinking if I bought some pvc fittings I could get my livewell to look like the guys in the video. Sadly I was wrong, anybody have any idea how he is getting his flow rite aerator to pump out such good flow? It only seems like my pump sucks in water only when I'm moving. Anybody have any ideas how to get my livewell to get air like the livewell in the video?

Use a 12V battery instead of 6V to increase your flow rate.
