Buy Indigo™ brand 0-2000ppm chlorine test strips to meet strict daycare regulations for meeting or exceeding sanitizing & disinfecting standards. Indigo™ brand 0-2000ppm chlorine test strips have color bars at 50-200 and 500-800ppm to do this for only $15.95 per 100 strips.
The color chart has ranges for sanitization (50-200ppm) & disinfection (500-800ppm). 800ppm is considered the maximum level for child safety in the event of ingestion.
You can use our free Chlorine Bleach Dilution Calculator to correctly calculate the amount of bleach & water needed to prepare the ppm levels indicated above. This calculator will allow for any concentration of chlorine bleach to be used to prepare a sanitizing/disinfecting solution but in this instance the video shows an 8.25% solution diluted to produce 650ppm (the midway point of 500-800ppm for disinfection as shown on the color chart).

Actual shelf life, if left unopened, is 5 years or more after purchase.

The table shows the amount of bleach needed for different ppm levels based on an initial concentration of 5% (most bleach sold in North America is rated at 5.25% but loses strength with time).
Choose a container large enough to hold the final amount of diluted bleach you want to make.
Measure & pour into the container the amount of 5% (initial) chlorine bleach you need.
Fill the container with water to the level of the Final Volume.
For concentrations other than 5%, use our Dilution Calculator to determine what you need.
If you are unfamiliar with millilitres (mL), you can use this Metric to American volume converter.
If you don't have the exact measuring tool, round up not down. i.e. for 47.5ml use a 1/4 cup.

We operate an Adult Daycare program and our local supplier, for these strips, stopped carrying them in the strength we needed several years ago. I found Indigo online and we get fast, efficient service with good pricing. Website is very "User Friendly". Very satisfied with this Vendor.
