You do know you can add the diffuser after it's filled right? I do it all the time in the ponds I fill and drain on an annual basis. My diffusers are mounted to garbage can lids with a nylon rope attached to the opposite end of where the air line comes in. I pull the assembly in slowly from the other side from shore until the air is coming up where I want it.

This works especially well in steep sided ponds where the diffuser can flip over.

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