Robarb20330A Pool and Spa 4-Way Pool Test Strips, 50-Bottle

I first got this product from my local Leslie's Pool store, then tried to order a different cheaper brand online, didn't like it, and ordered this one from Amazon, even though it's a little pricier. The little plastic canister is really great, keeps the strips dry. The color bars on the side are fairly easy to read. And you can read it immediately - you don't even need to wait 15 seconds like some others. So I like these. Tests for Total Bromine (which I heard is generally a good test for Total Chlorine as well), Free Chlorine, Total Alkalinity and pH. I still use the drop-based tests if I want a more thorough check (I do that once a week or two), but these are great for every day testing.
