When standard sanitation isn't enough, the BAQUACIL BAQUACIL® Algidefense® Algistat provides a specialized, fast-acting treatment to eradicate specific water chemistry threats before they escalate into full blooms.

Concentrated Active Ingredients

Delivers a massive payload of targeted treatment without adding unnecessary filler byproducts to your water.

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.
