Just thought I would update. We finally stopped losing chlorine overnight when I was out of town a week or so ago- figures I would do all that work so Hubby could have the fun of having the first good reading!! We totaled out at about 125+ gallons of bleach. I am now trying to figure out where to aim for with my CYA level - right now we are at about 55 and losing 5-7 ppm FC per day during the day (0 loss at night). The pool is in direct sunlight for at least 8 hours a day (maybe as much as 10) and for the last week or so we have been up into the 90s every day. I added 2 lbs of Di-chlor earlier this week to get the CYA to where it is now and we put 3 tri-chlor pucks in the chlorinator today to bump it up a little more. I am not wanting to add too much because we are going on vacation in a week and our plan is to bleach it up to a high shock level and fill the chlorinator - so we will be adding CYA while we are gone. We will also have someone check on things every couple of days (we will be gone 10 days). I'm thinking my goal will be about 70-75 for the CYA - I would prefer 60, but we are almost there and still losing a lot to sunlight every day.

Current Readings:
FC - 6.0
CC - 0.2
pH - 7.5
TA - 130
CH - 260
CYA - 55
