Because I take great care in keeping my pool water in shape (Thanks to TFP and TF-100) my pool builder is going to give me a discount to try a new product as long as I report back the results. He (and I ) use Natural Chemistry products which I have found to work fine. I used the Monthly Salt Water Magic kit, and the Fall and Spring Closing kits. I use muriatic acid and bleach as needed.
The product is called Foundation. Here is what it containssorry for the formatting, but I was copying out of a PDF)
Ingredient(s) CAS # Percent
Disodium salt of ethylenediaminetetraacetic acid 6381-92-6 5 - 10
Sodium tetraborate pentahydrate 12179-04-3 40 - 70
Boric acid (H3BO3) 10043-35-3 30 - 60
Lanthanum sulfate 10099-60-2 1 - 5
As best I can tell it looks like borates which is similar to what I have read on this site. And something I was going to try this year anyway. This may just be an expensive way to add borates!!!! Anyway, does anyone see anything harmful in this product?
I check my water weekly with TF-100 kit and follow the TFP guidelines for Salt Water Pools. Once locked in, the only thing I add is a weekly does of muriatic acid to keep the pH down.
Thanks for the help!
