Shorty,

I have three of them. Two 7feet by 7 feet. And one 10 by 10. All but one are on the bottom of the pond next to the pier acting as structure when not being used. I believe they will last longer underwater.

1 1/2 inch PVC and the three cornered PVC fittings are available from Stoney Creek Equipment Company. http://www.stoneycreekequip.com/

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