Performing a prophylactic SLAM even though water clarity is amazing. But given higher than desired FC demand and that the filter has required backwash more frequently in the past and I am about to go on vacation, seamed prudent.

SWCG Boost and power increase should have increased FC significantly. Filter pressure is up, and flow rate down to 10-15, too low for the SWCG apparently.
Jacked up FC with bleach and will backwash/clean filter tomorrow.
No signs of algae bloom and pool is crystal clear. Will monitor chlorine demand to see if a SLAM is necessary.
This threw off the test. Looked like it was holding steady, this could all have been due to low flow.

Increase cell power to 2, and started boost. Looks like cell power 1 is not sufficient in the middle of the summer. And the ORP reading with CYA @ 70 just essentially keeps the cell at a low %/power while the sun is up. Bather load is normal, last few days at very high UV levels

Pool pump would not prime in the morning for several days while out on travel. This led to drastic drop in FC and rise in PH due to no automated control. Result is visible algae growth on walls of spa.

Just replaced the main board on the SWCG. Set to 80% so should see rise of ~1ppm in 4 hours.

Suspect that the main board in the SWCG is going bad. Chlorine production is less than half of what is predicted, when using either of my relatively new generic cells or the brand new OEM cell. Part on order. SWCG is currently set at 80% (last summer similar chemistry set up operated at 30-35% in July). Will supplement with liquid Chlorine and stay on the high side just in case it totally craps out.
