Thanks for the advice, Wasser. That's what I ended up doing on my 72.

Wasserpest IMO the "no free lunch" thing applies here.

If you start to cut into the impeller, you will get more turbulence, but less flow, and most likely you will throw it out of balance which might cause a noisy, vibrating pump and over time mess up the impeller.

What do you want to accomplish? This pump is already pretty good in smashing up bubbles, and if you add the sponge on the outlet, most of them are being dissolved almost immediately. Have you tried simply turning up your CO2?

If the levels in the tank are too low for you, consider adding a manifold and add a second needle valve and Mini Elite.

DIY needlewheel for Hagen Mini-elite?

Hey guys, Im using a mini-elite to chop up and distribute my DIY co2 around the tank...it really looks like its doing a good job to me. BUT after reading about EI dosing, it appears theres a lot of emphasis put on CO2 levels being the next weakest link once all of the nutrients are taken care of...so...I want to try to make the mini-elite even more elite.

I was wondering if I were to remove the impeller from it and cut a couple slots vertically down each impeller blade with a coping saw or something would work? Would it still have the ability to move water like a powerhead? Or are needlewheels only good for chopping up and not movement of water.

Thanks for any tips. I guess I could just go buy another one for 10 bucks if I were to ruin the impeller..
