Men!!
Well the only test I was able to get this morning was the ph. It was 8.0. There wasn't ANY chlorine in it. My husband put 1 gallon jug and 4 3-quart jugs of bleach while I was at the gym. (MEN!!!) On the positive side, the water is now a light green. Still cloudy. Do I just let the bleach circulate for another day or so until it clears up?
On the right track
Adding 4 gallons of bleach will raise the cl in your pool by about 11ppm. So, adding the amount your husband did was OK. Actually, you need to test 3x a day and each time add enough bleach to shock your pool back up to around 12ppm. When we know your cya reading (which we need to) we can better advise as to whether this is high enough of a chlorine reading to kill the algae. Keep your pump running 24/7 while you are fighting the algae.
The other thing I can advise you at this point is to try and bring your ph down to around 7.4 or so. Add a pint of muriatic acid slowly in front of a return jet. Be careful not to inhale the fumes or splash any on yourself or the pool liner. After several hours, retest the ph and redose as needed to get the ph down to the target. Better to add small doses of acid and get there gradually rather than try to hit it with one dose.
We really need to know those other numbers. Please post them as soon as you can. Then somebody here can help you further. Hope this helps.

Pool test results
Okay, I just got back from the "pool store". (And laughed all the way out. She tried selling me Calcium Hardness again for my VINYL pool. And when I questioned her about it she said "you still need it because it acts as a barrier for the machinery". WHATEVER!!!) Anyway, here's the results:
FC .1
TC .4
CC .3
pH 8.2
CYA 9
ALK 55 (adjusted alk was the same)
I added one more gallon of Clorox (all I had left until tomorrow) and put 2 tablets in the skimmer. (May as well used the darn things up since I wasted the money on a WHOLE bucket full of it!!) I also ordered some more stabilizer solution so I can test the CYA myself again.
I have a question. The sheet said my temp. was 85 but there's NO way!! It feels more like 55 or so to me. I know the car ride there must have altered it in the 10 minutes it took to get there. Would it also affect the other results any?
one more thing
One more thing, she didn't even say anything at all about the algae. Shouldn't she have been able to tell from the water that it had algae in it?
It'll be fine to use the tablets as you need to raise your cya level anyway, needs to be 30-50ppm. Your pH needs to come down to about 7.4-7.6 and the tablets will help that too, so I'd stick with the tablets and shocking with bleach, but don't pour the bleach anywhere near the tablets . . . The important thing here is just making sure you maintain chlorine at about 12 ppm, this may require testing the water everyday or maybe even twice a day. Add the bleach at night, test in the morning, get it back up to 12 ppm, then test later in the day and add enough to get back up to 12 ppm, repeat until the algae is gone or dead. Also bringing your Total Alkalinity level to around 100 - 120 will help keep your pH level a little more stable. You really need a titration or DPD-FAS test kit for testing higher levels of chlorine. That would make this process a whole lot easier for you. What are you testing with now? The pool store? I don't see how your FC could be .1 when you just added 4 gallons of bleach yesterday, is the pool getting full sun all day or something? . . .Hope this is helping . . .

Yes, apparently it received quite a bit of sun that decreased it so much. I put the bleach in at the deep end jet away from the skimmer. I'm going tomorrow to get more bleach. How many jugs do you think I should buy? I recall last year a guy telling how to test the higher levels but I can't recall HOW he did it. Something about multiplying something by 10? I so hate that all the other data was destroyed. (Poor Ben!!) Maybe he'll read this and post the info again. I think it was pouring two of the tubes of test water into a glass and adding the drops or something. Janet may remember, she's quite the genius! So, should I deal with the alkalinity at the same time I'm trying to deal with the algae? I pulled up the calculator and according to it, I need to add 16.9 POUNDS of Borax??? Is that right? That'd be a little less than three boxes, correct?
Right now I only have the AquaChem test. It has seemed pretty darn accuarate so far. I only went to the pool store today because I was out of Stabilizer agent and needed that result. (I ordered some- for free!- early this morning and will receive it next week.)
You are using the borax calc for the wrong purpouse. It's not for pH. Please read the borax calc page closely.

It's the algae that is consuming the chlorine. When you want to test high chlorine with a kit not designed for it, just add 3 parts distilled water to one part pool water, mix and test. Multiply your result by four.
