Hello,
I have had a hard time keeping my chlorine levels up. My husband has doubted me using the BBB method because he sees us adding bleach multiple nights of the week. I know there must be an error on my part though. Basically I add 1.5 gallons of 6% every other night. I have a feeling I should be adding more bleach, but then it doesn't seem like it works out to be a cheaper deal.

Another thing that I have noticed is my CYA levels might be low. I did raise them a week ago to 50 from 25, but when I checked 7 days later it was back down to 25. Are the chlorine and cya levels related? What number would be ideal to maintain?

I have not needed to backwash in a few weeks. I have had to add water about every 3 days because of rapid evaporation though. I never knew I would have to add water so much. I bring it to the mid point on my tile and 3 days later it has dropped to below the bottom of the tile.

I don't really know what numbers to look for in Alkalinity and Calcium either. Should I be using those various calculators? I would love to know some set numbers that I can always aim to keep the water at for each of the categories below .

Here is what I tested:

FC 0
CC 0
TC 0
pH 7.5
ALK 110
CAL 140
CYA 25
TEMP 86

I appreciate you advice and time.
