I have been reading a ton about chemical balancing and maintaining my pool as I want to be rid of my weekly service and take care of it myself.
Here is where I am confused...
My service comes once a week and therefore I know any chemicals (chlorine, etc.) are only added once a week. My pool has always been very well balanced as indicated by the reports left by the maintenance people and random testing I do with my Taylor to double check service reports.
I have a 15X30 inground gunite with cartridge filter. We also have a cage over the pool. We live in south florida so the pool is open year round. We have never drained or partially drained our pool in 9 years and we do not use any type of chlorine system (inline or otherwise). We have also never had an algae issue in 9 years.
Everything I read maintains that chlorine has to be added multiple times a week if using unstabilized because iris not adding CYA to slow the usage of chlorine. If I use stabilized tabs I run the risk of too much CYA increasing the need for FC and things will just get out of control over time.
I want to be able to service my pool once a week just like my current service has been doing for years without having to pay them.
How do I add the needed chlorine only once a week without running the risk of FC going low or CYA running to high?
I absolutely know it is possible because pool service companies all over the country are doing it weekly on millions of pools. My pool service has been doing it once a week for 9 years without ever having an issue so, I know it is possible for me to do it as well.
There is something these pools services are doing that is not being discussed online because, everything I read says unstabilized chlorine means adding multiple times a week and stabilized means high CYA that cannot be removed with atleast a partial drain / fill.
There has to be some balance they are using to be able to continually keep the pool balanced while only adding chlorine weekly.
I am totally baffled.
