Widen the pattern and slightly increase the flow of a MaxiJet powerhead pump with just a couple of common hand tools.
I agree I also have to mod kits on two 1200 but with this mod it seems to push more of a stedy strem with more power. With the sureflow it's a wider strem.A very interesting mod. Personally, I think that if you are looking for flow you might be much better off to purchase a Sureflow mod and Suregrip magnetic holder. I'm using 2 modded 1200 pumps in my 8' long 200 gallon and have to use the smaller propeller because the large one blows sand all over the tank. If you want flow, that is a great way to get all you want at a reasonable price.
