The ATi pumps are modded nicely, the venturi is very well done. With the Ati you can seal the sicce pump up so its kind of a no brainer as to if you have it right. These however are just the basic pumps and pieces are supplied, so its like go get'em tiger.

However, I am usually OK at this DIY stuff, and I can not get this pump to operate correctly. I mean I messed with it for hours last night and again this morning.

It seems the problem is the mesh mod, maybe there are too many layer of enkamat. But, I am barely pushing it past the rubber seal on the volute cover, and when it fires up I am not getting peak performance from it, and I am getting microbubbles released fromt he pump into the water. I am luck I have mine in a 10 in deep tank at eye level to work on, I can't imagine having to pull it in and out of a sump.

Anyway, so far I can not get the pump sealed correctly in order for the mesh wheel to operate at optimal efficiency.

If anyone can tell me how they have theirs working good, I would love to hear it.
