For the budget minded, this is the perfect option for when you run out of test material, but don't need another full kit. Strips may be torn in half for 72 uses or cut into quarters for up to 144 tests. Comes with an accurate 5.5 to 8.0 pH chart in 0.2 point increments and easy to understand instructions on the correct use of pH strips which are the same high quality used in the full Home Test pH Kit.   We recommend the complete Home Test pH Kit or the Home Test pH Kit Book if you do not already have the full kit. The refill does not contain information or instructions on how to raise or lower pH levels. Knowing how to balance pH levels is as important as knowing the pH reading.
