I will try to get TC at the level the best guess chart suggests at around 6 or 7 so I will be OK with my CYA and will see how the CYA will drop over the summer with backfilling and so on.
You mention a sprayer for the returns. Were can I get this type of things? I would like to have something similar as the 10 kinds from the street we live in, think the water is still to cold to swim.
