I'm thinking about maybe using a circle cutter -- Looks like a pencil compass, but instead of the pencil it uses a blade. I know I'll have to go round an' round several times to get through it, but I don't have any other ideas on how to accomplish this task.
I know someone else here must surely have made filters before, so what did you use to cut your holes? Any suggestions would be appreciated. Pond is not large -- something like 2000 gals. Going to meter it this spring to be sure, but that's a fair guess.
Edit: Oh, one more thing. I will be running this as a secondary filter. Since I don't have a bottom drain, I wanted to get as much filtration as possible.
