Ok.. here we go
CYA TEST
Fill dispensing bottle to 7ML mark with pool water.. (Little plastic bottle witha flip top cap)
Fill to 14ml mark with R-0013
shake bottle for 30 seconds
Hold comparator at waist level with 2 fingers, back to the sun shading the tube
SLowly teansfer mixed solution to samll comparator tube until black dot just disappers when viewed from the top.
As soon as it disappears, that is you level. IF you can still faintly see the dot, keep going until its gone
IF the dot disappears between lines, you reading will be the next highest. (disappears at 35, your CYA will be 40)
With the amt of stabilizer you added, it would have put you at CYA 33 if your start level was 0. Even if you started at 30, you shouldnt be above 60
If you are still getting mixed readings, pour the tested solution back into the bottle and do it again.. you can keep doing this test over and over with the same sample
Hope this works
