What It Treats
Bottom Muck & Sludge
- Digests organic bottom sediment
- Reduces muck depth over the season
- Removes decaying grass and leaves
Fish & Wildlife Waste
- Eliminates fish and waterfowl waste
- Reduces nutrient load that feeds algae
- Supports a balanced pond ecosystem
Water Clarity & Odours
- Breaks down odour-causing organics
- Improves overall water quality
- Works best paired with aeration
Macro-Zyme is a biological treatment, not an algaecide — it works by consuming the nutrients and organic matter that cause muck and odours. Results build over weeks of regular application.
