Program to record testing results?

[GraceByDesign]

I have an Excel spread sheet that I just designed. It is pretty much just for record-keeping, but I did put in some 'conditional formatting' so if a value is outside the recommended range, the font will be a different color. Just a small help to me so I don't have to always be comparing values.

I also put the CYA chart there. I plan to modify it (ETA: the spreadsheet*) after we actually get the pool with an area that will tell me how much to add to MY pool (ex: 2 2/3 cups 6% bleach to raise Cl by 1 ppm, if I get a 10000 gal pool)

This is for an AG pool that I plan to keep CYA at 30-50; no heater, so I am not worried about CH.

(Edited) PM me if you are interested in a copy. You may feel free to modify it if you wish.

*ETA: I did not mean I would modify the Best Guess CYA chart I meant I would modify my spreadsheet to include such things as how much bleach I need to raise my pool 1ppm.
