I'm not sure about the pond care. My main concern would be the pond pump/filter as that is directly in the pond. I have to pull it out and clean it periodically. I think I will cross that bridge when I come to it! The snake seems to be getting very comfortable with us viewing him. Today is the first time that I have seen it during the day. It has it's home under the pond itself. The snake has been peeking out of it's hole and coming partially out all morning. We got some very good head shots of him that let us properly identify it. That being said, the Florida banded water snake has a mouth full of teeth and will bite if antagonized. I'm not sure if he would consider me coming by and cleaning the pump now and then antagonistic. Do they sell "snake suits" for use around snakes to keep one from being bitten??? LOL
