Oh, shoot, I forgot a couple a questions about the testing process. When testing the Cal, and you are adding the drops from Cal 3 bottle, do you stop when the water is clearly blue from the side, or when you can see blue from the top?

And the instructions indicate for those people using Ozone to add two drops of the #3 bottle before the 5 drops from the #2 bottle. Is this if you are only using a ozone system, or does it include those like me who are using both a SWCG & ozone system?

Thanks and sorry about the goof,

Mike
