High Head / low power consumption return pump

[subnet88]

Im running inin-sump pump. I have tried the L1 and it wasn't much more real-life flow than the Jaebo. I'm pretty sure the modded off the shell tank I use for my sump is tempered glass, so I can't drill for an external pump.

I used the Danner Pondmaster 6000 for a while,m and it provided the flow I wanted, however the stainless impeller warped and destroyed the pump.
