Pond Bomb — Powerful Natural Bacteria Treatment for Crystal Clear Water
Transform murky, green pond water into sparkling clarity with our Pond Bomb Treatment — a revolutionary natural biological treatment that harnesses the power of beneficial bacteria to restore and maintain a healthy, balanced pond ecosystem. Unlike harsh chemical treatments that can stress or harm fish and aquatic plants, this entirely chemical-free formula works with nature rather than against it. Each pond bomb contains billions of live beneficial bacteria cultures and enzymes that rapidly colonise your pond filter, decompose organic waste, reduce harmful ammonia and nitrite levels, and outcompete the algae and harmful bacteria that cause murky green water. Treats ponds up to 20,000 litres per bomb — making it suitable for the vast majority of UK garden ponds.

When to Use Pond Bomb Treatment
- Spring pond startup after winter — reactivate biological filtration
- After cleaning or replacing filter media — restore beneficial bacteria colonies
- Following water changes — re-balance the biological ecosystem
- When water turns green or murky — rapid bacterial boost
- After treating fish for disease — restore bacteria killed by medication

How to Use
-
Calculate your pond volume — length × width × average depth (in metres) × 1000 = litres
-
Drop the bomb — simply drop directly into your pond near the waterfall or filter inlet for best distribution
-
Do not disturb — avoid major water changes or filter cleaning for 5–7 days after treatment to allow bacteria to establish
-
Turn off UV sterilisers — UV light kills beneficial bacteria; switch off for 5 days after treatment (optional but recommended)
-
Repeat as needed — monthly maintenance doses keep biology at peak efficiency
