Algae starting to form on pool walls,

[Rancho Cost-a-Lotta]

Don't forget about this:

Do you have a water softener for the home? With high calcium fill water, CH levels will continue to rise with evaporative top offs. If you can hook your fill line into softened water, you may never have to do RO again.

I do have a water softener for the house. I will check into connecting it to my pool fill line. Sounds like a good idea.

In sunny southwest, consider bumping up CYA to 50 ppm. It will take a bit more chlorine initially, but daily FC loss should drop.

Pool looks good!
