Hi Ben -

Here are my numbers from yesterday and today:
6/28 930 am FC - 5-5.5 CC = 2-2.5 pH 7.2 ( still)
pucks dissolved so added 1 new trichlor puck and 9 oz of borax

530 pm FC= 4.5 CC= 2.5 Ph still 7.2 added 9oz borax

today 6/29
930 am FC = 5 CC=1.5 ph still 7.2
230 pm Fc = 3.5 CC = 1.5 pH still 7.2 alk 60 CYA <30(but the black dot was obscured if I filled the tube to top so there is some in there)
puck dissolved so new one added
7pm FC= 3.5 CC= 1-1.5 pH still 7.2

Questions:
1. I added 2.5 to 3 lbs of CYA on saturday - is today's CYA level accurate at 4 days out? do I need to add anymore or just retest at a later date? I think my chlorine is not too unstable.

2. Ph is very stable at 7.2. alk is now 60 - what should I do at this point? keep adding borax? or use baking soda? because I am using trichlor, which is acidic, will I need to constantly be adding borax over the summer?

3. Why does using trichlor tend to decrease CCs? ( I am happy to see it happening before my eyes!) does that mean I wont be able to use liquid bleach at all? what will I do for shocking?

4. What FC am I shooting to maintain? Am I able to go away at all and leave the pool for a few days? I have no idea how to do that and not screw up the chlorine levels.

Hope to try some swimming tomorrow and will let you know how it goes! Thanks. aciam
