Hello! My pool guy has informed us he is raising rates understandably because of increases in prices for chemicals ($30 a month more) so we’re debating if we should begin taking care of it ourselves because we’re already questioning his methods. Occasionally we’ve had our pool tested at a local pool store and they tell us our CYA is too high (last test at store on 7/30/22 was 161) and to partially drain or throw in the water hose for a few days. My pool guy says the cya is fine, there’s no algae and the water is clear. Of course he has to keep the FC levels high to manage the pool with a high CYA. I bought a Taylor k-2006 C test kit and here are my levels below. Should we drain, start over, and do it ourselves or pay him more to keep using TriChlor and keep increasing the cya? I just don’t feel experienced enough to test and add liquid chlorine myself every day. Other pool companies have said I need to completely drain and power wash the plaster to get rid of cya in the plaster. Is this true or would just a partial drain and refill be good enough?
With these levels what would you recommend for a 18K gal pool with these levels?
