We don't recommend Nature2 units, but it's unlikely that your unit had anything to do with the pool problems you're having. Do this:

1. Complete the Pool Chart, so we can tell what you have:
Pool Chart Entry Form
Pool Chart Results
2. Get a good test kit -- 'guess-strips' don't count, no matter WHO reads them or HOW they are read:
+ 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.)
HTH 6-Way Test Kit @ Walmart
Taylor K2006A (3/4 oz bottles) @ Amazon
Taylor K2006C (2 oz bottles) @ Amazon
3. List the chemicals you've been using over the last 2 months, by EXACT pool chemical name and EXACT brand. (Similar sounding chemicals can have VERY different ingredients and effects.)
