OK, this is the best photo I've taken this year. Photosynthesis happening on pots in our fish pond. Enlarge it if you can on your desktop to see more details. This little pond gives us so much joy. Just have to clean the filter weekly and not add more than 1/5 of the volume of new water at a time. We put the fish in a trash can full of water with a bubbler that was running for at least a day when we clean out the pond every late spring.
