last weekend, we "upgraded" our koender's windmill aerator by replacing the standard tubing w/ 300' of weighted tubing and removing the airstone for a vertex rubber diffuser.

i noticed that the old tubing had been damaged ---looks like a critter's been chewing on the tubing.

we've had beavers living in our pond for a few years and it looks like they've found another way to drive us CRAZY!!!
any ideas to protect the new tubing?
