You’ll see results on floating weeds or algae in 3-7 days and submerged weeds in 17-21 days.

Our recommendations

How to apply – Floating Plants and Algae

• Dilute with tap water, and evenly spray the surface over the plants
  • Dilute 1 oz. in 1 gallon of water
• If using with a surfactant, dilute products with tap water, and evenly spray the surface over the plants entirely
  • Dilute 1 oz. Bayflox and 1 oz. of surfactant in 1 gallon of water

How to apply – Submerged Plants and Lake Weeds

• Review the product label to determine appropriate amount of product for your target treatment area. (Approximate coverage of each size bottle by dividing how much it treats up to by the average depth of your treatment area in feet)
• Mix with tap water and spray over treatment area. (You will notice Bayflox clouding up and dispersing through treatment area)
• Boost results on submerged lake weeds by tank mixing with Dibrox and Mizzen. Can mix all three and spray at once.

When to apply

• Apply on a sunny, calm day when the water temperature is 60° F or warmer
• Treat early in the morning, and when plants are actively growing and near the surface of the water
• May re-treat every 7-14 days or when there is new growth

Other tips

• Application rates based on a 1 ft. average depth, areas with dense growth may require a higher rate to be used
• Mix with surfactant for floating and emergent plants
