The CYA in my pool was 0, then went up to normal after adding pH up and now is back to 0. What do I use to make it stay where it is supposed to? Do I need to go buy stablizer?
How do I make the CYA levels even out?

Ph up has nothing to do with your cya level. You should add CYA/stabilizer when you know what your test really shows--if you need any. What is normal?
It may have been after I added the alka up.... I have been trying to figure out what is missing... it is no longer green, but still cloudy. Also, is it safe for the kids to swim with the current levels?
I am not authoritative here, but since you are just starting out with getting you pool going on BBB, I think you should keep all of you posts on this pool in one thread for now. It helps the people here help you. What are you using for you tests?
The only thing that raises your CYA is by adding more CYA. In any case, you have no CYA in your water and that means that after about an hour on sunlight, your FC will be gone and then your pool water will be unsanitized.
I would suggest adding enough CYA to get you to at least 30 ppm. Then add enough chlorine to get you to at least 4 ppm. Overall, I would suggest reading Pool School. That way, you can understand the reasons behind why certain levels are suggested.

Strips often show CYA at 0 when it really isn't. They can not measure CYA under about 40ppm, and even at 40 they look close to zero.
If CYA is at or above 50 they will show some change to match to the 50-100 color, but it's still very inaccurate.
The test that will tell you what the CYA level is in the TFT100 and the Taylor K-2006 but it's a reagent test, not a strip. It too is not perfect, with a +/-10ppm accuracy depending on light and operator perception but it's a heck of a lot better than the strips for CYA. They are absolutely junk and will steer you wrong every time if you use them to calculate chemical additions.

How are you testing?
How do you chlorinate your pool?
P.S. It's better if you put the test results in the post and not in your sig. When replying to your posts you can't see the sig, just the posts.
