We started using H2O2 in our swimming pool These test strips help us to keep the levels accurate. Easy to use and easy to read. Very happy with the product and with the results in our pool!
Perfect to balance H2O2 in hot tub.
Good to know. Some of the hot tub vendors who have contacted us over the years recommend the 400ppm hydrogen peroxide strips. Both are effective but outdoor hot tubs may be more susceptible to windblown algae as well as H2O2 breakdown due to sunlight.
Great service; price and product. Canada Post dropped the ball. Paid extra for express post and package sat in Canada Post for 3 days then delivered on day 4.
Thanks for the feedback. Many of our Canadian customers have had similar problems. This prompted us to write: Canada Post is in the way of small business competing against Amazon.
Great friendly service , always helpful and h202 strips high quality
