Pure Pond Sludge Bomb Duo Pack is an all-natural pond treatment pack containing 1 x PURE Pond Bomb and 1 x PURE Sludge Bomb to help improve pond water quality, clarity, and overall pond health. This duo pack is ideal for koi ponds, ornamental ponds, self-contained water features, and pond systems that need extra biological support.
The PURE Pond Bomb is a fast-acting, concentrated version of the award-winning PURE Pond. It contains a powerful blend of friendly bacteria and enzymes that begin working when the ball enters the water. These bacteria help clean up organic waste, break down ammonia and nitrite, and support clearer, healthier pond water.
The PURE Sludge Bomb is designed to digest sludge and organic waste that can build up in ponds and filters. Excess sludge may lead to poor water quality, reduced oxygen levels, odour, algae issues, and increased maintenance. PURE Sludge Bomb helps reduce this build-up naturally, creating a cleaner and more oxygen-rich pond environment.
Pure Pond Sludge Bomb Duo Pack can be used together for a complete pond boost or separately when a specific result is needed. Simply drop the Pond Bomb or Sludge Bomb directly into the pond, filter, or biological filter stage. Each bomb treats ponds up to 20,000 litres.
Choose Pure Pond Sludge Bomb Duo Pack if you want a simple, natural pond treatment to reduce sludge, improve clarity, support ammonia and nitrite conversion, and reduce pond filter maintenance.
