Hi! New to pool ownership and have found this website so helpful- thanks! I have a few questions:
1. the pool we inherited has a pebbletec surface- does that mean it is fiberglass, vinyl or plaster? Or none of the above?
2. how long does it take for an accurate CYA reading after draining water to lower the levels? We had a pool service managing the pool until Sunday when we discovered algae on the wall and realizes the CYA went from 30ppm at the beginning of May to over 150ppm. Long story but lesson learned to know how to manage your own pool! We’ve drained and refilled about 1ft. It’s probably not enough but not sure how long it takes for all the water to mix in and dilute it. I’ve shocked the pool with 3lbs of shock 2x since last Wed and haven't added any more tablets that have stabilizer. Maintenance was performed on Mondays so not sure if I should also add 2 tablets today?
3. if the CYA HASNT come down to a reasonable range then how much more water should we drain?And is it ok to drain water below the slimmer baskets if I close the slimmer drain?
