  • Concentrated 3‑in‑1 formula that clarifies water, prevents scale and corrosion, and protects pool surfaces and equipment during winter months.

  • Safe for all pool types: in‑ground, above‑ground, chlorine, bromine, saltwater, and SoftSwim® systems.

  • Treats up to 25,000 gal per 2 L bottle; half dose for pools ≤12,000 gal to save product.

  • Easily administered by slowly pouring around the deep end while the pump runs, followed by two hours of circulation.

  • Compatible with BioGuard Arctic Blue winter kits—but powerful enough to be used on its own.

  • Ideal as a final closing-step to simplify spring start-up and reduce maintenance.
