Ok. I'll make a note that the other one needs to be deleted.

Order the Taylor K-2006 kit from my signature below and since it is only available online, get a kit to use in the meantime. 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.)

I would also suggest that you read a thread in the "Pool Chemistry for Intex-Type Pools." The thread I want you to read is the second stickied thread at the top of that forum.

Come back with further questions and we'll go from there. Hope this helps.
