Hello, hoping someone can help me out...I have a Waterpik Technologies test kit that tests chlorine and pH with OTO and the Phenol drops. Problem is I can't find the instructions for how many drops and can't seem to find it online anywhere. I've seen 5 drops a lot but my sample container is very small compared to other kits I've seen. Is there a ratio of OTO drops to water sample size? I'm trying to find a better test kit but my options are limited where I am and will need to order online, since I won't be using the pool store after finding this site!!! Was complaining to my neighbour i couldn't get alkalinity plus anywhere in town and then found this website and fixed the problem with baking soda
Second year with the pool and have no significant issues that I could see....I would like to be able to more accurately test my chlorine levels properly (without going to the pool store for analysis and then feeling like I HAVE to buy what they recommend!) in case something is going on that I can't see.
Would appreciate any help I can get with the OTO radio till I can get a better test kit
