This weekend (a beautiful set of Spring days) was consumed with renewing the fountain that is an integral part of our front courtyard. My experiment with shutting down the the filter/pump over the winter, resulted in a very ugly environment of algae and slime (with fish casualties). The lessons of experience.
Three plants survived and now the fish (with additions) will roam a crystal clear aqueous home. The fountain now in it's fourth year of operation has been a fun hobby for me and source of great pleasure - maybe even FLOW :)
So the fountain yields happiness; happiness can extend your life - yes indeed a fountain of youth.
