Having drianed and refilled my pool and getting everything back on track the TFP way i was wondering about my CYA levels . I live in Thailand where the temp doesnt really drop much below 30°C most days and can reach 40°C+ sometimes , the pool is in direct sunlight all day and last year in the when it was 40°C the pool water temp hit 35°C . I have got the CYA up to 40 now and was wondering what people recomend for these conditions i see pool math recomends 30-50 but my conditions might be a might more to the higher end of average any one else living in these conditions what CYA do you run , thanks for any help
