Simply Test Strips – for Use with The Sirona Simply Chlorine-Free & Bromine-Free System for Spas & Hot Tubs, 25-Count Bottle (82120)

I really like this system it is easier than any other I have tried no guessing

I only use Sirona products for both of my hot tubs and the test strips work fine.

I use the Serona system as a whole so I feel like I really can’t use any other testing strips, but I have to admit that the colors are so close together that I find it a bit difficult to know exactly what the levels are sometimes. In the end, it is a simple and fairly easy to use product.

Love testing for their chlorine free hottub products

I use these to keep the water in my cold plunge where it needs to be. These are super simple to read, only take a few seconds, and combined with their treatment protocols helps me go a lot longer between water cycles.

Very good test strips and even better price on Amazon! So expensive in the pool/hot tub stores!

Yes approved!

Work great HOWEVER its a very expensive alternative to using Chlorine or Bromine because you have to use there own test strips to test there products.
