Applied Bio Swimtrine Plus Algaecide – Part #4009910 (1 Quart)
Product Overview
Swimtrine Plus is a high-concentration copper-based algaecide designed to eliminate green and mustard algae quickly and help prevent re-growth. It’s suitable for chlorine, bromine, salt water, ozone and mineral pool systems.
Key Features
- Contains approximately 9.3% copper as the active ingredient.
- Triple-chelated formula for better stability and fewer side-effects.
- Effectively kills green, mustard and other algae types and helps keep them from returning.
- Can be used in a wide variety of pool systems (chlorine, bromine, salt, ozone).
Technical Specifications
- Part Number: 4009910
- Size: 1 Quart bottle (approx. 32 fl oz)
- Application: In-ground and above-ground pools that require algaecide treatment.
Usage Instructions
- Ensure pool water is circulating and filter is operating before treatment.
- Refer to the dosing table (based on pool volume) on the bottle label. Typically, add the required dose directly to the pool water with pump running.
- After addition, allow full circulation and monitor water clarity, algae presence and copper levels as directed.
- For algae prevention, apply a maintenance dose at regular intervals (often bi-weekly) as suggested by manufacturer.
Applications & Compatibility
This algaecide is appropriate for both new algae outbreaks and preventative maintenance in residential pool systems. It works with traditional chlorine or bromine sanitation, salt chlorination, mineral systems and ozone systems. Always verify pool volume and system compatibility prior to adding.
Troubleshooting & Maintenance Tips
- Algae not clearing: Confirm correct dosage, ensure filter is clean and functioning, and that circulation is adequate.
- Cloudy water after application: Check copper level and filtration status; run the filter until clarity returns, then test chemistry.
- Staining or metal-type discoloration: Monitor copper levels and ensure product is used according to label instructions to prevent metal buildup.
Maintenance Tip
Maintain your algaecide treatment as part of your regular pool service routine. Keeping residual prevention levels and ensuring circulation and filtration are in good condition will help minimize algae outbreaks, reduce cleaning time and protect your pool investment.
