John,

I've seen that. However you can move even more water more efficienttly if you build "yamabuki' airlifts that are completely out of PVC.

Do a search for yamabuki air lifts. I am running my 1000 gallon aquaponics system with only an air pump with one 1.5 inch yamabuki airlift. The Europeans are moving 15 ft3 of water (66 gpm's) of water with a 10 watt air pump that moves only 20 lpm of air.

If pigs could fly bacon would be harder to come by and there would be a lot of damaged trees.
