healthy wiser 9 way water test strips

Healthywiser 9 way water test strips is good because you can tell what's in the water. Instructions are simple. You basically did this trip into water and removed immediately and then hold horizontally for 30 seconds and then compare the colors for each of them. These include total alkalinity, free chlorine, pH  total hardness, total chlorine, cyanuric acid, nitrite, nitrate and bromine. I have a problem because I cannot tell of any differences in the colors of the strip after I placed into water. There's a hundred test strips and it kind of hard to open it comes in box with instructions. And the bottle that holds them has and aluminum foil tab and about 3 foil packets.
