I saw my neighbor power washing the rocks on his pond/waterfall. I didn't get to ask him why, I assume he wanted to clean algae from the rocks. The pond gets a lot of sun throughout the day. Is this bad for the bio filter?

well your just taking off the algae, off the rocks an not using hot water that would kills the good germs
If the Bio-filter is turned off for more than a hour, BB will be killed off. The BB on the rocks will most likely be nuked as well.
