Hi! We just bought a home with a saltwater gunite pool. It’s 24,700 gallons. After the previous owner left there was about a week that no maintenance at all was done and algae was taking over rapidly. We hired a local service to perform a “green to clean” service and are hoping to maintain ourselves from there. I know I need salt, and a water test kit, but beyond that I don’t know much as we have never owned a pool. We are also planning to purchase a Polaris 280 to clean debris from the bottom. Any recommendations would be greatly appreciated!! Attaching photos of the listing picture of the pool and the pool in its current state for reference.
