With 18,000 gallons, 50% setting and 8 hrs run time, you will be adding about 1.7 ppm per day which should be OK depending on you CYA. Check it after a day or two and see how it goes.
Thanks Nas. It's been running like that for a couple of weeks. I need that CYA reading. Outside of the solar, our pools look to have similar equipment.

Are you thinking the cleaner is for the navigator that cleans the bottom of the pool?
