Clear Spa Hot Tub Balancing Chemical Bundle Includes pH Plus, pH Minus, Alkalinity, Calcium, Test Strips, LeisureQuip ScumBoat, and Hot Tub Care Guide E-Book

I haven’t figured out which one it is, but one of these chemicals leave a strong yellow line at the water level. It may not be this brand, it might just be my water. The line is easy to wipe off so I still recommend this product. No smell, easy enough to remove the caps, clearly labeled and easy to use.

This is the best way to buy spa chemicals as this set gives you the most commonly needed chemicals all in one bundle. This is the second time I have used these and I am very pleased. My only suggestion would be to include a measuring scoop with each bottle or at least one for the set.

I like the chemicals. They are easy to use and last forever. Only issue I have is that the test strips do not match what was advertised and they are very hard to read and only measure 4 not 5 levels. Strips should match the chemicals. Had to get my own strips.

Easy to use and adjust chemicals

Ended up returning before using as it was cheaper in person at our local store. Product has worked great so far though

This was exactly what I needed at a very good price along with testing strips

Bought this for my parents as I bought them a hot tub. They are in their 70s.The package arrived a week before their hot tub. Easy to read and easy to figure out what needed to be done.
