FC = 3 CC = 10 TA = 90 CH = 290 CYA = 45 I know he is using some kind of tabs as I see them in the skimmer basket from time to time. No back washing as we have a cartridge. My wife has noticed he does pour some liquid into the pool that causes a smoking effect when it contacts the water. The CYA does rise but never to outrageous numbers so,in know it's possible to maintain once a week. Think about it, there are thousands of pool guys handling millions of pools nation wide on a once per week basis. I find it hard to believe they have some "magic formula" for keeping everything in line when all the posts I read online are saying it isn't possible without out of control CYA levels or some other kind of back reaction. Everything I read online is saying pool owners have to continually add chlorine at a minimum every 3-4 days These guys are doing it once a week and it blows my mind that I cannot find anything online saying how they do it. Actually everything I find online says it can't be done. It is being done every week all over the country. We also have never drained or even partially drained / filled the pool in 9 years.

I have been reading a ton about chlorine usage and the changes that occur with different types. On residential pools, like mine, our pool service comes once a week and they seem to be able to keep everything balanced just visiting 1 day a week. They do provide a report showing the readings ae good and the pool seems to be fine. I have a Taylor test kit so I can spot check and the readings are also always good. In reading I understand that tabs will raise CYA to unmanageable levels over time and the alternative is liquid chlorine which has to be added to the pool more often. We are in Florida so the pool season is year round. How is my pool guy able to keep the pool balanced on a once a week visit without FC depleting and CYA levels getting out of control? I guess the real question is how can I do the same thing once a week and stop paying him? Thanks in advance!
