Everything was going great with the pool as far as balancing the chemicals. The water was looking great. Went on vacation this past week on Tuesday and just returned last night. Before I left, I made sure everything was in line. I then put in a couple of 3" pucks in my IC to provide some chlorine while I was gone. I also new it would raise my CYA about 4ppm but that was fine as I had kept it on the low side knowing I would be taking a couple of vacations this summer.
Numbers before I left for vacation:
FC - 5
CC - 0
pH - 7.5
TA - 80
CH - 200
CYA - 35
Number from after vacation using pucks:
FC - .5
CC - 0
pH - 8.2+
TA - 80
CH - 200
CYA - 35
I get up this morning to brush the pool and clean out the skimmer baskets. I see a couple of small brown spots on the swim out. I think maybe they are dirt but they don't come off after brushing. Any ideas on what they may be and how to get rid of them?
Also, any idea why the pucks didn't keep up the FC?
