Got some results. At 4am this morning I took a water sample so I could drop off at pool store this morning. Also added 5.68 gal more of bleach. Results from this mornings sample after adding the 5.68 gal of bleach and 1.5lbs Borax last night are:
FC - 1.0
TC - 1.4
CC - 0.4
ALK (input) - 225
ALK (adjusted) - 205
PH - 7.4
CH - 400
CYA - 60
At 4pm today I took a new sample to have tested after adding the 5.68 gal bleach this morning and results are:
FC - 3.6
TC - 3.8
CC - 0.2
ALK (input) - 154
ALK(adjusted) - 130
CH - 292
CYA - 73
I could not believe it held chlrine today so at 5pm I took another sample to a different pool store and results are:
FC - 3.8
TC - 3.9
CC - 0.1
ALK (input) - 114
ALK (adjusted) - 82 what is the difference?
PH - 7.2
CH - 293
CYA - 96
Both stores use the PINPOINT water analysis system but ALK & CYA #s are way different. One store has me listed at 22000g & the other has me at 21000g. Could this be the difference? Also, when I told the "pool guy" I went to this sight for info and was using bleach he was impressed but said the bleach could ruin my liner. Should I be worried? Don't want to get my hopes up but looks like it held. Water is crystal and was 100* here today. Pool gets full sun from 11am to 6pm. What's my next step. Thanks again evderybody!!

You need to still work on getting you FC level up... With your CYA, you really need to be at 5 to 10 for normal and I think the mods might tell you to get it up to 20 to shock it since you've never achived that yet...

The difference in CYA and Alk could well be because of the difference in reported volume, I don't know....

Like Evan said, now that you're starting to hold chlorine, I would shock it up to 20 just to kill off the rest of the CC, and see if that doesn't make a difference in the demand.

The next time you talk to your pool guy that said bleach (which is 6% sodium hypochlorite) would ruin your liner, ask him why liquid chlorine (10-12% sodium hypochlorite) won't? It's funny to watch them hem and haw around that. Bottom line is, they're the same thing, but bleach is half strength, and easier to deal with (and if you're from Louisiana, the key word is AVAILABLE!). Of course, if you splash it directly onto the liner while adding it, it will discolor in those spots, but if you're careful when adding it NOT to splash it on anything, once it gets into the water it breaks down into chlorine and salt water. Nothing there that will hurt your liner, if added in the right amounts.

Looks like you're on your way to easy poolkeeping!!!

poolguys are used car salesman at best.That's like saying dont spin that .38 caliber handgun on you finger it might go off and kill you..you really should be spinning this .44 magnum instead on your finger

Sounds good. I will shock up to 20. Hopefully I get my test kit tomorrow and wont' have to go to pool store. Awesome help. Thanks again!!!

BTW sorry if I offended a "good" used car salesman on this forum>I meant to say a "bad,over anxious,obnoxious,about to be evicted,late with the child support,gotta make a sale NOW,used car salesman"

I know I need to add some Borax to bring up PH. Wife is nagging to swim. I said no cause to much TC. Am I correct? Sorry for all the questions.
