You can get the Taylor K-2006 or 2006C from the test kit page link in my signature below. Good decision to get one! In fact, since you think you have WAY high CYA, you'll have to have this kit because you will have to run higher than normal chlorine levels. See the Best Guess Chlorine Chart in my signature. Since the K-2006 is only available online, you'll need a kit to use until the good kit arrives. Get a cheap OTO (yellow drops) / phenol test kit, or if available at YOUR Walmart (check availability), get the HTH 6-way DROPS test kit, which is compatible with the Taylor K2006. Test the pool as soon and you can, and post the results. If you get the 6-way kit, ALSO test the water you FILL the pool with, especially if it's a well, and post THOSE results as well. (The HTH is the best available kit you're likely to find locally, but it's not the K-2006. It can only provide rough measurements chlorine levels above 5 ppm, and it measures "TOTAL" hardness, rather than "CALCIUM" hardness, which is not ideal.)


Please fill out our pool chart with your pool's information. It makes it easier to help you.

Also, post a current set of water testing results taken with a drops-based kit. Tell us what type of kit you used to get the results. Then, with the requested information, someone here will try and give you some advice.
