Thanks, everyone. I didn't get to work on the pond today - went shopping to try to find an Easter dress - when did all the dresses for sale get so DARN UGLY? I did buy a nice tee shirt with waterlilies and a frog and irises, though!
Guess I'll get them up soon. I see pads down there, a few are almost at the surface, and the string algae is gearing up big time.
In my pond, which is 26" deep, the deep part is MUCH colder than the top part.
