well..that's what i expected would be the case..here is what i was told to do if you want to check me:

-add pool water up to a line on the vial that they gave me (about midway).

-fill the rest of it with the test reagent provided to test for CYA (fyi,it's taylor test re-agent and it's not old chemicals..supply that came to local store via calgary agent which is the western canadian authorized supplier for taylor)

-shake the vial for 13 seconds then pour it into the test tube with the black dot on the bottom.

-fill the tube just until i can't see the dot, then look at the reading on the scale on the side.

the mixture was absolutely clear. water was taken from about an 18 inch deep level in my pool.

sound right? i'll do a double check right now but...
