–Ran the pool pump up to 3,400 to get rid of solar bubbles. It pretty much quit–because the water level, which I had just increased, was too low for that much pressure. I dropped it down to 3,200 and added a bunch of water. Bingo! Pressure is between 15 and 20 psi and there are zero solar bubbles. Dropped it to 3,000 and everything held. Will drop lower and try to find a speed that works. I have a vague recollection of doing this before and giving up when the bubbles returned after a while. Hope to do it better this time, and maybe run the pool at a slightly higher than desired rpm for a shorter time every day, watching to see when it hits temperature.
–Watched an episode of Dr. Blake with horrible subtitle sync. Watched S05E04 of Rick and Morty; stupefyingly bad.
