I have been using Jacks Purple for several years......works great. Purchased this product from MKM pool supplies at a good price and free shipping on purchase of 4 bottles. Very happy overall.
Jack's Magic The Purple Stuff is the stain preventative of choice, and a must product for salt / chlorine generator pools. Unlike traditional sequestering agents, The Purple Stuff works extremely well in high salt and high TDS pools. The Purple Stuff keeps silica in solution while greatly reducing the incidence of cell scaling in salt / chlorine generators.
- A must for salt / chlorine generator pools
- A must for high TDS pools where the water is already full of salt and will not accept any additional metals or minerals
- Ideal for pools maintained with liquid bleach, eliminates "clouding" when bleach is added
- One quart treats 10,000 gallons
