Hi Bill, We are the manufacturer of Pool Time products. The test pads will have some color right out of the bottle because of the reagents that each of the test pads contain. These colors will change once they are dipped into the water. If you have any other questions, please give us a call at 1-800-252-7665.

Yes it can.
Yes, and it is MUCH faster, easier and cheaper than the traditional CYA drop test!

Dip the test strip about 12 inches into the water and then compare the visual color squares with the ranges on the bottom to determine the chemical levels. Easy to use.
