My dad brought me a sample of his water to test alkalinity as they were getting a wierd result which I just duplicated with my fresh test kit.
25 ml of water, added 5 drops of indicator which turned the water green. At about 250 drops of titrant the water turned yellowish orange, kinda like the ph indicator for 7.2. More drops did not turn it any shade of red like it's supposed to. I stopped at 30 drops.
Their pool has 100+ ppm of CYA, and I now have their bleach at 15+ ppm. Is this interfering with the alkalinity test? Ph is registering as 7.2.
If the high bleach is the issue, should I add the chlorine neutralizer drops I have from my old test kit then retest, assuming I have any of it left?
