BioGuard 28-40 algcicide
BioGuard Algicide 28-40 is used to prevent algae growth in your swimming pool. This economical algaecide may foam and may not be used with spa treatment or in pools with attached spas, water features, or jetted returns.

Initial Application 16 oz per 25,000 gallons of water
 
Maintenance Dose 4 oz per 25,000 gallons per week.
 
 Ensure all pool equipment is working properly. Clean or backwash filter following manufacturer's directions. Adjust pH to between 7.2-7.6. In outdoor chlorinated pools, add stabilizer to establish a minimum level of 30-40 ppm to reduce the degradative effects of sunlight upon the chlorine residual. Check for metals and if present add a stain and scale inhibitor to prevent staining of pool surface due to metal. Maintain sanitizer residual in accordance with label directions found on your sanitizer of choice. This product is effective in controlling the growth of green and blue-green algae. When using other products as outline in directions for this product, always follow directions on those products.
