FAQs

What is pond sludge and why is it harmful?

Pond sludge is a layer of organic waste—including leaves, fish droppings, and uneaten food—that accumulates at the bottom. It promotes algae growth and can lead to foul odors and decreased oxygen levels.

How often should I apply pond sludge remover?

Most products require application every 2–4 weeks, but frequency depends on your pond size and sludge levels. Always follow the manufacturer’s instructions for best results.

Are pond sludge removers safe for fish and pets?

Yes, most sludge removers use natural bacteria and enzymes that are safe for koi, fish, aquatic plants, and wildlife. Always double-check the label for safety guidelines.

Can sludge removers eliminate algae?

While they don’t directly kill algae, they reduce organic waste that feeds algae blooms, making your pond less hospitable to green overgrowth.
