Mark, when i put the air lines in i used 3/8' rebar 20' lengths , over lapped the joints bout a ft., make sure to connect the rebar to the diffuser plate or you could break the fitting , i just used plastic ties , nicer than bricks and no chance of kinking the line and small chance of snagging up on it. put some bricks on the plate. measured from pump to where i wanted them , cut the line and installed the rebar , put rubber membrane diffuser in boat and was pushed out from shore , real easy. your job lot bigger though lol.go to photobucket and type in kenspond , i couldn't figure out how to make it work from my profile page (duh).those pics are when she was built. when my lilies take off this summer i will post the finished pics. lots work , but i love it when i'm back there , my retreat from the world. \:\)

i only wanted to have some fun
