return pump

[FishyFishy!]

I vote buy a new return pump that suits your needs. But if that is not an option, there shouldn't be a problem with cutting back the flow with a valve.

The Maxi-Jet wouldn't even make a trickle in your tank. I had a MJ1200 return on my Fluval Edge nano, it was about 2 ft head back to the tank... and it barely had any flow at all.
