Good seasonal pond prep product
I use this mostly as a seasonal prep product when the pond starts getting colder or when I’m opening things back up. It’s easy to add and seems to help keep the pond a bit more stable during those awkward spring/fall transitions. Not a magic product by itself, but as part of regular pond maintenance it makes sense to have.
