I'm reviewing pool school and manufacturer recommendations and there are differences. I'm assuming the plaster manufacturer (we have quartz aggregate) isn't taking into account SWG v chlorine as there's not mention of either in their literature. Here's their recommendations:
a.] pH 7.4 - 7.6
b.] Alkalinity 100 - 125 ppm
c.] Calcium 250 - 400 ppm
d.] Chlorine gradually to 2 ppm
e.] Total dissolved solids <1000 ppm
f.] Cyanuric acid <50
The items are bold are the ones that differ from BBB. I don't want to void my warranty, yet everything I've read in pool school about SWG and CYA makes sense.
What do you folks do? Whose recommendations do you follow?
