Adding BBB

(my current CYA reading at opening is 56) and suppose I don't have algae, do I still need to shock on a weekly basis? Is the need to shock determined by the level of CC? If yes, what's the upper limit of CC ?

How are you testing? Most CYA tests do not have the resolution to give a reading like 56 ppm. Even the $1000 colorimeter/turbidity meter we use at work is +10/-25 ppm for the CYA test.

The colorimeter at the pool supplies store.
My Taylor kit is due any day now. Does it have a better res?

Are thet usuing a colorimeter with either liquid reagents or dry reagents in a vial or are they using a strip reader with test strips?

The store tech pipetted the water samples into sealed rectangular shaped vials that must have contained reagents (I'm not sure if they were liquid or dry) and then she took the reading off the colorimeter.

Ok, That would be a LaMotte Waterlink or Waterlink Express. It's a pretty good system. We use the same at work. I will warn you that the TA test often reads low and so does the calcium hardness. It has to do with the limitations of the meter so if your Taylor test reads higher on these believe it.

My Taylor kit is supposed to arrive any day now.
Is the test's chem based on titration? Does it offer an accurate reading?

which Taylor kit did you get? Hiopefully you got a K-2006 and not a K-2005.
