Question--is it ok to use the heater in a vinyl-lined pond? I'm guessing I'd have to make sure it stayed away from the sides so it doesn't melt the vinyl?
Plants are not an issue with me, either--the goldfish and the turtles ate 'em all, lol.
FYI, we just bought a farm stock tank de-icer at the pet store that has a a couple of rings around it to keep it off the plastic. Said it is safe to use in plastic lined pools. Thought it was kind of expensive at $70, though. Probably could have got it cheaper at the feed store.
