Well the new pool is wonderful (thanks to all of you) but I will be gone for 10 days and am not sure what to do. Neighbors will be testing but not daily. Here are my numbers this morning. Do they look right?

FC 4.5
CC 0
TC 4.5
pH 7.5
ALK 80
Cal 30
CYA 25
Temp 82

I have been adding about 1/2 gal chlorine nightly and numbers stay fairly consistent. I have some 3" tablets but have never used them I see that some people do when going out of town. Will a tablet hold the chlorine for a few days? We have sun 2/3 of the day and will run the sand filter 4hr in am and 4 in pm. Any advise will be greatly appreciated.
