For starters, crumple that up and throw it in the trash. 
Pool store testing is usually garbage (and their "correct" range is completely wrong).
Next, get a complete test kit, we recommend the K-2006C, or the TF-100 (the TF-100 has the absolute best value for the amount of testing reagents you get - you can find it here: TFTestkits.net ). Once that test kit comes in, get us a complete set of test results:
FC
CC
pH
TA
CH
CYA
Based on what I'm seeing from the store test, your CYA is at least 100, if not higher. This means you're going to need to drain the pool at least 50% to get it under control. With the heat and sun we're now having in AZ, this may have to be done carefully over time. Once your kit is in, we'll be able to get a good CYA reading and give you better advice.
While waiting for your kit, add a half gallon of plain, unscented concentrated bleach a day into the pool (make sure it is not splashless or EZ-Pour). This might help to keep you from getting into worse trouble. Remove any and all solid chlorine products - pucks, powders, etc from the pool immediately to avoid raising that CYA any higher. You're going to want your pool to be on a bleach only diet until we get some reliable test results.
What does your water look like right now? Do you have any pictures of the pool you can share?

The good news is that you don't have a swamp!!! Very nice looking pool.
So we urgently need to get the chlorine level up while we're waiting on that kit. We're going to make a bad assumption right now that your CYA is 100 (99 on a pool store test usually means "off the scale", so it could be higher). Let's use PoolMath to go from 0 to 13FC based on this chart: Pool School - Chlorine / CYA Chart
Enter your pool's volume, select bleach as your chlorination method, put the percentage of your bleach into the strength spot, enter 0 as your current FC, and 13 as your target. How much does that tell you to add?
