Common Questions & Instructions
Should I add this while the pump is off?
No, targeted chemicals require thorough circulation. Keep your pump running for at least 12-24 hours after application.
Can I swim immediately after dosing?
We generally recommend waiting at least 2-4 hours after adding specialty chemicals, or until the entire volume of pool water has turned over once.
