Leaving pool for four days

[tlevy]

Pump and SWG will be running. Question is - do I leave the solar cover on or off?

Thanks for your perspectives!

IMO I would leave it off. It's beneficial for the sun (UV) to hit the pool.

If you leave the cover on it will reduce evaporation, you will have less PH rise if your PH tends to rise and your FC consumption will be lower. If you leave it on the CCs will build up and the water will get hot.
