In The Swim Algaecide 60 Plus for Swimming Pools - 1 Quart

In The Swim Algaecide 60 Plus is a targeted liquid treatment designed to prevent and control algae in both above-ground and in-ground swimming pools. It addresses four major varieties: green, yellow, black, and pink algae. Because it relies on a non-metallic, low-odor, and non-foaming formula, it suits complex backyard pool setups that include attached spas, waterfalls, or decorative fountains where bubbling foam would otherwise be an issue.

This treatment is pH tolerant, meaning it works effectively in both acidic and alkaline conditions without requiring you to rebalance your water chemistry before pouring it in. It is also compatible with pools that use well water, and it blends seamlessly with common sanitizing routines including chlorine, bromine, biguanide, and salt systems.

Dosing depends on your pool volume and current water clarity. Standard prevention requires an initial dose of 6 to 11 ounces per 10,000 gallons, followed by routine maintenance doses of 2 to 4 ounces per 10,000 gallons. Active, visible algae blooms require a heavier treatment of 11 to 17 ounces per 10,000 gallons, which will consume a 1-quart bottle faster in large pools.

Verdict: In The Swim Algaecide 60 Plus is an excellent choice for pool owners wanting broad algae control across various sanitizer types and water features without worrying about foam or strict pH balancing beforehand.

A great fit if you:

• Manage an in-ground or above-ground pool with water features like fountains, spas, or waterfalls.
• Need to eliminate or prevent green, yellow, black, or pink algae.
• Use well water or run chlorine, bromine, salt, or biguanide sanitation systems.
• Want an algaecide that works without adjusting pH levels first.

Consider something else if you:

• Prefer pre-measured tablets or shock packs over liquid measuring.
• Need a treatment size larger than a single 1-quart container for multiple large pools.

Will this algaecide create foam in pools with waterfalls or spas?
No. The formula is non-foaming, making it specifically formulated for pools with attached spas, waterfalls, and decorative fountains.

Do I need to balance my pool pH before adding this product?
No. The formula is pH tolerant and functions effectively in both acidic and alkaline pH ranges, so you do not need to alter pool chemistry prior to application.

How much product should be added for routine maintenance?
For standard maintenance, use 2 to 4 ounces per 10,000 gallons of pool water. Initial dosage requires 6 to 11 ounces per 10,000 gallons, while treating visible algae takes 11 to 17 ounces per 10,000 gallons.
