Polyquat 60 Algaecide for Swimming Pool, Highly Concentrated, 32 oz

PoolSeason Polyquat 60 Algaecide is a concentrated liquid treatment designed to tackle active algae blooms and provide ongoing preventative control in swimming pools. Whether you manage a standard backyard setup or a commercial facility, this 32-ounce formula offers a targeted solution for eliminating green, black, and mustard algae varieties.

Because it is formulated without added copper or other metals, the liquid avoids surface staining on vinyl, fiberglass, gunite, and plaster finishes. It is also non-foaming and will not cloud pool water. The formula works alongside standard sanitation methods, maintaining full compatibility with chlorine, bromine, and saltwater systems without requiring immediate pH adjustments or disrupting routine water chemistry.

In terms of application, a single quart bottle can treat up to 40,000 gallons of water. It can be integrated into regular weekly maintenance routines or used during seasonal pool opening and closing periods. The formula scales across various pool types, working in small plunge pools, standard above-ground setups, and larger inground installations.

While the concentrated strength allows one 32-ounce bottle to cover large volumes, the product data does not specify exact dose markings on the bottle or detailed treatment intervals for heavy infestations versus light weekly maintenance. Pool owners with much larger commercial setups may also need multiple bottles on hand for full seasonal coverage.

Verdict: PoolSeason Polyquat 60 is a reliable, metal-free algae treatment for owners of inground or above-ground pools looking to clear up water blooms without causing surface stains or foam. It is especially well suited for chlorine, bromine, or saltwater pools requiring strong seasonal or weekly maintenance.

A great fit if you:

• Need to eliminate green, black, or mustard algae in an inground or above-ground pool.
• Want a non-foaming algaecide that avoids surface stains on vinyl, plaster, fiberglass, or gunite.
• Run a chlorine, bromine, or saltwater sanitation system and want simple water maintenance without pH disruption.
• Are opening, closing, or routinely maintaining a pool up to 40,000 gallons.

Consider something else if you:

• Prefer pre-measured solid tablets or single-dose packets over liquid measuring.
• Need a larger multi-gallon bulk package for high-volume commercial needs in a single container.
