BioGuard Pool Closing Complete® is the final piece to a perfect pool closing and clean pool opening in the spring.

  • Saves time at spring opening by controlling waterline buildup
  • Protects equipment and surfaces from developing scale or corroding
  • Specifically formulated to counteract pool water’s increased corrosive tendencies during the cold weather months

BioGuard Pool Closing Complete® is a 3 part formula that protects against corrosion in the cold water, prevents scale deposits common in winterized pools and fights waterline buildup. All of this combined makes for a clearer and easier to open pool in the spring when you want to enjoy it. Perfect for use with Arctic Blue Winter Kits.
