Megan, welcome to TFP!

To help keep you on track, please ensure that you review/bookmark the vital links below in my signature. You will refer to them each season. As for the test strips, they are not reliable. Neither is pool store testing. They may seem convenient, but the testing errors causes you to spend more money in the long run. If you have a larger pool (over 3K gallons) you would do best to obtain one of the recommended test kits - either a TF-100 (link below) or Taylor K-2006C. They cost a little $$ upfront, but will save you a lot of headaches over the season. So proper (home) testing is priority #1.
For cloudiness/algae, you need to "SLAM" (link below). Those instructions work, but again, you need one of the proper test kits. While waiting, you could buy a 5 or 6-Way drop test kit from Walmart for under $10 that will help you for perhaps a few days. But that's just a temporary thing - better than test strips though.
Lastly, don't forget to update your signature with your pool type and equipment. It will help us later as we try to help you. Great to have you with us.
