BioGuard® Pool Closing Complete


BioGuard Pool Closing Complete provides the final touch for pool closings. The concentrated 3-in-1 formula helps save time and prevent issues at the opening as well as protecting pool surfaces and equipment during the cold weather months. This product clarifies the water, prevents waterline build-up, and removes phosphates. This product works perfectly with the BioGuard Arctic Blue Winter Kits.

What's in the Box

  • 1 x BioGuard® Pool Closing Complete 


  • 3-in-1 pool closing formula.
  • Saves time at spring opening by controlling waterline buildup.
  • Protects equipment and surfaces from developing scale or corroding.
  • Specially formulated for cold water temperatures.


Before Applying BioGuard Pool Closing Complete:

  • Make sure all pool equipment is working properly, including pump, filter, skimmer and heater. If needed, backwash and/or clean filter according to manufacturer’s directions. Follow manufacturer’s directions for winterizing equipment.
