This is my first post but have read lots of posts over the past year.
I live in England but have a home in Turkey.
My pool is a concrete in ground tiled overflow channel pool, 11m x 5m x 1.7m deep. It also has a 3m x 3m x 1.7m balancing tank. Test kit LaMotte, Color Q Plus 2056. Taken care of by local pool store when I am not here.
It is 7 years old and runs from the beginning of May until the end of October. The options in Turkey are tablets, Dichlor granules, liquid chlorine and SWG. I am using the Dichlor granules I'm afraid. From start up until July the CYA increases to an unacceptable level beyond the chlorine/CYA table. I then get green grout lines that require brushing every few days.
From the knowledge I have gained from this site it seems common sense to me to go for an automatic liquid Chlorine and Acid pump with a weekly dose of the Dichlor granules to keep the CYA level correct. One of my friends has a SWG system but to be honest I don't like the idea of corrosive salt in my pool, hey, but that's just me!!
I am probably no where near as experienced as you chaps so therefore I am asking for opinions as I want to make a decision on this very soon.
