Good but so expensive. More than 2X pricier than amazon. I got it from the master distributor in Ontario directly. Guess it will more expensive from Pool dealers, if they sell or order for you.
Done all test for once. CYA test reagent goes very quick. Can only do 4 or 5 CYA test. Why don't Taylor put more for CYA test? There are plenty of space in the box.
Hope the kits can last to the end of summer. Will think another way to get reagents.
