Moved into my house almost a month ago and I have a pool that I believe is roughly 20k gallons. I've begun to get a little bit of algae growth. I go out there and scrub it occasionally as well as having one of the pool vacuums that runs when the pump is running. This is my first home so I don't have ANY pool experience but want to maintain it myself. With the house came some equipment (pictured), as well as bucket of chlorine tabs as well as a bottle of pool perfect + phos free. I also have an Ozone generator.
I dont know how to adjust pH, what it should be, or anything! HELP!
