Alkalinity Test requires you to add drops until red, starting about 16 drops was pink, by drop 21 like a fushia pink. Do you keep adding until a true red?
To increase CYA via granular stabilizer, place the required amount as calculated by the Poolmath calculator into a white sock and place in the poolside skimmer basket. For those concerned about suction flow to the pump, suspending the sock near a return jet or from a floating device will also suffice. Best never to allow undissolved granules to rest directly against the pool surface. Squeeze the sock periodically to help it dissipate. Once dissolved, consider your CYA adjusted to that programmed (target) level. CYA test readings should show a rise in 24-48 hours, however some pools may experience a longer delay to fully register. Best to confirm final CYA in about 5-7 days before adding any more stabilizer/conditioner.
CYA test- says to fill tube until you can no longer see the black dot. I filled mine to the very top and could always see the black dot.
Is it ok to run your SWG while the Cya is being dissolved? I also need another 40ls of salt, can I add this while Cya is dissolving?
