Additional Information

How To Use Poolife™ Back to Blue™ Shock System

Application Method

  • Retest and balance water before resuming normal pool use

Dosage Instructions

  • 1 kit treats up to 15,000 gallons of pool water

Frequently Asked Questions

Q: What is Poolife™ Back to Blue™ used for?
A: It’s designed to rescue green or algae-covered pools by shocking, clarifying and restoring water clarity within 24 hours when used correctly.

Q: Do I need special equipment to use this?
A: Yes. You must have a pool vacuum that can vacuum to waste, as the product drops debris to the bottom for removal.

Q: Can I swim right after using this?
A: No. Wait until chlorine levels return to a safe range (1–4 ppm), and all debris has been removed.

Q: Will this affect my pool’s water balance?
A: It may temporarily raise chlorine levels. Always test and adjust pH, alkalinity and calcium hardness after treatment.

Q: How long does the full treatment process take?
A: Most pools will begin to clear within 24 hours. However, actual results depend on water circulation, vacuuming efficiency and the severity of the algae. Proper follow-through is key.

Q: Can I use this kit as a regular shock treatment?
A: No. Back to Blue™ is formulated for emergency cleanups and algae recovery — not for routine chlorination. For weekly maintenance, use Poolife™ TurboShock™ or Rapid Shock™ instead.

Q: What happens if I can’t vacuum to waste?
A: This system requires vacuum-to-waste capability to remove the flocculated debris. Without it, the dead algae may recirculate and cloud the water. Consider using an alternative shock-only product if vacuuming to waste isn’t possible.

Q: Is this safe for vinyl-lined pools?
A: Yes. When used according to label directions, the system is safe for all pool surfaces, including vinyl, fiberglass and plaster.
