I also have a lot of algae growing in the falls and streams now.
I have a TON of algae growing on my water fall and on the bottom. I mean it's everywhere.
December weather is here. I have a little bit of ice on the pond. I think it's only going up to 32* today.
I unplug my little pump that is on the bottom of the pond because I don't trust the flex pipe that is exposed to the weather. I don't know how it will react to the freezing weather. I do leave my waterfall run all year.
