Hi, i have a palintest tablet count kit for ta which seemed to be ok when the ta was higher. it was around 90 but my ph kept rising so kept adding a little more acid. now that ph seems to have stabilized i don't know what the ta is because when i add just one tablet it goes to light pink straight away and as i add more tablets it just gets darker. it is supposed to start yellow and then turn deep pink. so im guessing this is because the ta is low but i don't know how low. has anyone got one of these kits and got any suggestions?
Does anyone have any experience with the palintest cool pooltester? This is a budget photometer and i wondered if these are accurate and would solve my problem. these are supposed to be able to measure ta between 10-500 ppm. would this be in increments of 10 as well.
