OK. I'm finally back. BTW, love you Watermom. We did not change the sand! Please don't be angry but I went to Leslie's and got the big test kit they have, and it's the K2005. I realized this after I tested the water and was thumbing through the book. My levels are as follows:

FC 3
TC 3
CC 0
ph 7.8
TA 110 ppm
CH 100
CYA 100+ (probably 120)

I did add stabilizer tabs once pool was filled. Something is off, though as it's taking 3 tabs daily.

What do I do now?

Thanks!
