Description
Koi Pharma® Pond Defender is an advanced all-in-one water conditioner that instantly detoxifies harmful compounds and supports fish health during water changes, transport, spawning, or illness. It restores the slime coat, replenishes electrolytes, stabilizes alkalinity (KH), and protects against pH shock - keeping your pond safe and stable 365 days a year.
Key Benefits
- Instantly makes tap water safe. Neutralizes chlorine, chloramines, ammonia, nitrite, and heavy metals - including copper.
- Slime-coat & stress support. Replaces the natural slime coat lost during handling, transport, or water changes to reduce stress and promote healing.
- Electrolyte & alkalinity boost. Replenishes essential electrolytes and lifts alkalinity (KH) for stronger biological filtration and long-term water equilibrium.
- Buffered pH stability. Helps prevent sudden pH swings - one of the leading causes of shock in pond environments.
- Year-round use. Effective at any water temperature.
- Safe for all aquatic life. Formulated to be gentle yet effective for koi, goldfish, and other ornamental pond fish - even during spawning, transport, or illness.
- Compatible with most treatments. Safe for use with most other water treatments and pond medications. See label for restrictions regarding use.
