We can save you SO much money by NOT selling you anything! All you have to do is follow the TFP pool care routine. We buy our chemicals from Walmart, Lowes, Home Depot, even Sams/Costcos. Here is one example: "TA is raised by adding baking soda" as seen in this link:

I want you to look close at the two different tests. Notice how different the CYA was 45 vs 28. The only way to lower CYA is to drain/replace water. That alone shows you one of the many reasons we don't trust those kinds of tests. Getting your own test kit like we suggest will save you so much money. Look at the link Gene
@proavia shared with you in his post above for the test kits we use. $50 a MONTH for the membership for a test that is not as good as you were lead to believe as you can see from your test results is a lot of money.
