here's a blow by blow pictorial of the mesh mod for the maxi jet 1200/900
1. cutting the impellar blades with a dremel
2. putting a bottom layer of gutter guard on top of the cut impellar blades
3. put one layer of mesh on top of the gutter guard and sew it on with fishing line,
then trim it so there's no interferance with the volute cover
4. for the venturi i used these pieces that came with the maxi jet pump,
i cut the 2 little pins that stick out of the sides of the venturi half way down,
that way it fits into the pump imput very snug,
if you cut them all the way off it will be loose and need silicone/plumbers tape.
then i put the smaller of the 2 screens that comes with the maxi jet
over the other end to prevent debris from clogging the venturi imput.
pictured is an expensive air valve, probably overkill for this venturi,
get a cheap one at home depot or lowes in the gardening supply,
it's black and it's for a water drip lines
here's a shot of the complete pump
and a couple pics of it working on a cpr bakpac, the bubbles it made are extremely small, much smaller than before the mods, the skimmate in the cup is from almost 1 hour of skimming with the cup about half way down into the skimmer

i'd say it easily doubled the power of the bacpak if not more, unfortunately i had no air meter on hand at testing, but the results were awesome!!
