XtremepowerUS 5-Way Swimming Pool & Spa Water Test Kit, Chlorine, Bromine, pH, Acid Demand & Total Alkalinity Testing Kit with Color Chart & Case

Gives accurate results and received quickly. Pleased with this purchase.

Beautiful in my pool

got it quick.

My favorite test kit, had one like this several years ago and it is one of the better ones..More info and charts to looks things up on.

The results are a little off on ph and alkaline but I enjoy a good chemistry experiment!

it's worth getting a Taylor brand. this one works but the accuracy isn't nearly as good as Taylor brand

Not for commercial uses

For example, the chlorine test says fill small test file to the line then add five drops of number 1 Solution Pl. cap on vile swirl to mix. There is no cap on the chlorine test. How am I supposed to do that? Do the instructions tell you how to do that? No, they do not tell you how to do that. I had an incredibly awesome test kit before that had three separate files and the chlorine and pH were on its own separated vial and it had a lid on it so all you had to add water and then put your drops and put the lid on and shake it up. It was incredibly easy but now I can't find that kit anymore. This was the closest thing that looked like that and it's an absolute mess. If you are going to make your kit this complicated, then please provide some instructions. I'm gonna try to use this right now and if I can't get this working, I'm returning it.

I didn't get solution %231 to test chlorine levels, and instructions are vague. I will not purchase again. I wish you could subtract stars, because this would be a -5 from me

Don't buy this unless you know how to use a testing kit. The instructions are very vague
