I been following this board for 6 years since I bought a house with a pool. It has been a joy to open, maintain and close the pool myself over the years and saving $$$ isn't a bad thing
I have a 25,000 Gallon in-ground vinyl pool with a Raypac Gas heater, a Hayward Sand Filter, and an inline Hayward chlorinator . I am going to open the pool this weekend here in NY. The pool is green at the moment. I was a a pool store today to get my water tested and here are the results. I was surprised to see 0 for CYA. They advise me to get the CYA up with approx 10lbs of Conditioner. Do I put any shock in to the pool, tabs in the chlorinator first or just filter the water with the conditioner for a period of time? I would really appreciate any feedback to what i should do first and not make a rookie mistake on how to address the CYA being 0.
Thank you all in advance.
