Hey y’all, I’m looking to purchase an automatic pool water tester. I have narrowed it down to crystal water monitor and the water guru sense 2. I’m leaning toward crystal water because the water guru sense 2 cassette refills only come with one updated cassette and two of the older version. I think that’s ridiculous. I know most people don’t like automatic water testers, and prefer the manual method, but I have a very hard time reading them and I’m not paying my pool guy anymore cause I don’t think he’s doing a good job. Please don’t recommend I find a new pool guy because I’d rather do it myself. Does anyone have either of the two mentioned testers and prefer one to the other? Looking for all pros and cons
