We have a 17,000 liter above ground vinyl lined pool, located inside of a 'green house' to keep the bugs off us.
This year I switched to Borax, 12% liquid Cl, and muriatic acid.
Came back from a 5 day trip to a green pool. Took a sample into the local Surfside pool place to double check the ph level as I have had problems before with high Cl levels affecting the ph test, and they advised me I needed to add 20 liters ( yes, that is 20 not 2.0 ) of the 12% liquid Cl to go from 3ppm to 10ppm. And that liquid Cl was not as good as Dazzle Ultra Shock.
This sounded absolutely nuts to me. The pool calculator indicates the free Cl would be about 150 ppm if I did that.
Took another sample into the Dolphin pool store and the only number the 2 places agreed on was the ph of 7.6.
Both places indicated that Borax shouldn't be used..... And that I needed to quickly get my Ca from 130 or 150 (depending on which test you believe) up to 200. In a vinyl pool?
I should know better that to go into these places!
Anybody else get advice like this?
