Keep your pH between 7.0 and 7.8, and keep your chlorine at 3-6 at all times. Until you put some stabilizer in the water, this may mean adding chlorine a few times a day. I'm assuming you have around 13,500 gallon capacity? If so, then each 1/2 gallon of 6% bleach will raise your Cl by about 2.2 ppm, so you can use that as a guide. You need to add some stabilizer. You can get it at WalMart in the spa chemical section in a 4 lb container. It's sometimes labeled stabilizer, or conditioner, or balancer, but if you'll look at the ingredient label, you should see cyanuric or isocyanuric acid as the ingredient. Follow label dosing to get to around 30 ppm, but instead of broadcasting it, put it in an old sock and hang it in front of a return so it will dissolve. Once you have stabilizer in the water, then the sun won't consume the chlorine as fast and it will be easier to keep the levels constant.
While you're at WalMart, if they have the hth 6-way test kit (drops, not strips!) get that--it will measure most anything you're going to need to measure. Be sparing with the CYA test, though, because that kit only has enough reagent to test it 3 or so times. Don't retest for CYA until all the powder in the sock has dissolved. Once you have CYA in the water, you'll need to adjust your chlorine levels a little bit....take a look at the link in my sig for the "best guess chlorine table" for more info about that.
Enjoy your pool!!
