Pond Dye & Enzyme Blend for Large Water Features

Microbe-Lift Bio-Blue is a pond water colourant and beneficial enzyme blend that safely tints water a natural shade of blue while supporting the microbial ecosystem. The 5-gallon drum treats up to 320,000 gal (1,211,000 L), making it the right size for large decorative ponds, commercial water features, and stormwater retention basins where professional-scale application is required.

Blue Colour + Biological Support: Two Benefits at Once

Bio-Blue performs two roles simultaneously: it adds a natural blue tint that reduces light penetration to submerged growth and creates an appealing aesthetic for large water features, and it delivers enzyme support that aids beneficial bacteria in maintaining healthy pond cycles. Once diluted at the correct dose, Bio-Blue will not stain fish, birds, rocks, or most concrete surfaces. It mixes completely within hours of application. At 5 gallons, the drum is the most cost-effective format for treating large volumes repeatedly through a season.

How to Use

Calculate pond volume before dosing. Pour Bio-Blue near a pump intake or waterfall to ensure rapid circulation throughout the water body. Colour intensity depends on pond depth and volume, start at the recommended dose and adjust over subsequent applications to achieve the desired shade. Reapply as colour fades, typically every 4 to 6 weeks depending on rainfall, runoff, and UV exposure. At 5 gallons, use a calibrated pump or measuring container for consistent application rates. Store in a shaded, secure location near the pond.

Ideal for large ornamental koi ponds over 13,000 gal (50,000 L), commercial decorative ponds and resort water features, golf course water hazards, and any large-scale installation where a consistently managed water appearance is required.
