Description
Evolution Aqua PURE Sludge Bomb
Biological Sludge Remover for Cleaner, Healthier Ponds
The PURE Sludge Bomb from Evolution Aqua is a fast-acting biological treatment designed to break down and remove organic waste and pond sludge. Ideal for ornamental ponds and water gardens, it contains a concentrated blend of beneficial bacteria and natural enzymes, suspended in a nutrient-rich activating gel to kickstart microbial activity as soon as it's introduced into your system.
Built-up sludge—comprised of decaying leaves, uneaten fish food, fish waste, and other organic debris—can lead to poor water quality, unpleasant odours, increased algae growth, and reduced oxygen levels. PURE Sludge Bomb works to naturally digest this waste, helping to restore biological balance, improve water clarity, and reduce the need for manual cleaning and filter maintenance.
Key Features and Benefits
- Biological Sludge Breakdown: Targets and digests organic matter, including fish waste and decaying vegetation, at the bottom of the pond.
- Reduces Maintenance: Minimises the need for frequent filter cleaning and sludge vacuuming.
- Improves Water Quality: Promotes stable water chemistry by supporting the natural conversion of ammonia and nitrites into less harmful nitrates.
- Oxygen-Friendly: Helps increase oxygen availability by reducing oxygen-consuming organic material.
- Safe for All Aquatic Life: Non-toxic and safe for use in all ornamental ponds with fish, plants, and wildlife.
- Easy Application: No measuring or mixing required—simply place the Sludge Bomb directly into the pond or filter chamber.
Usage Guidelines
- Treats up to: 20,000 litres
- When to use:
- In spring to stimulate biological activity as the pond awakens from winter
- In autumn to reduce sludge before winter dormancy
- After heavy feeding or visible debris accumulation
- Application: Drop the PURE Sludge Bomb directly into the pond or filter box. For heavily stocked or problem ponds, repeat dosing may be beneficial.
Optimal Conditions for Use
- pH should be maintained above 7
- Chlorine and chloramine levels should be at zero
- Perform regular water changes to support biological activity
- Avoid using medications or strong algaecides in conjunction, as they may harm beneficial bacteria
Additional Information
- The product includes an activating gel that helps distribute bacteria more effectively.
- The rate of sludge breakdown will be faster in warmer water temperatures due to increased bacterial activity.
- Avoid over-dosing and always store in a cool, dry place away from direct sunlight.
- Wash hands after handling and keep out of reach of children.
PURE Sludge Bomb is a practical, natural solution for maintaining a healthy, balanced pond ecosystem—ideal for hobbyists looking to improve clarity, reduce waste, and promote long-term aquatic health with minimal intervention.
