Pond Medic Algae Clear
Keep your pond water clean, clear, and healthy with Pond Medic Algae Clear, a powerful treatment designed to control and prevent most types of algae in freshwater ponds. This advanced formula helps restore water clarity while preventing algae from returning when used as part of a regular pond maintenance routine.
Algae growth is often caused by excess nitrates, phosphates from fish waste and food, and strong direct sunlight. Pond Medic Algae Clear targets these conditions while remaining safe for fish and aquatic plants when used as directed.
Unlike many algae treatments, this formula contains no copper or heavy metals, making it a safer choice for long-term pond care.

Pond Medic Algae Straw
Control algae naturally with Pond Medic Algae Straw, a long-term, biological algae prevention solution designed for ponds and water features. Unlike chemical treatments, Algae Straw works by slowly breaking down in water, releasing natural micro-organisms and compounds that help inhibit the growth of algae and blanket weed.
This eco-friendly solution improves pond stability over time, making it ideal for ongoing maintenance and seasonal algae prevention.
Key Features
Natural, biological algae prevention system
Helps inhibit algae and blanket weed growth
Releases beneficial micro-organisms as it breaks down
Provides long-term algae control (up to 3 months per bundle)
Improves water oxygen penetration and biological activity
Suitable for ponds and outdoor water features
Non-chemical, environmentally friendly approach
Benefits
Helps reduce reliance on chemical algaecides
Supports long-term water clarity and balance
Works continuously once activated
Encourages a healthier pond ecosystem
Helps prevent algae blooms before they start
Ideal for seasonal pond maintenance
How It Works
Algae Straw works through a natural decomposition process:
The straw bundle gradually breaks down in the pond
Natural micro-organisms are released into the water
These organisms inhibit algae and blanket weed growth
The structure provides maximum surface area for oxygen and water interaction
Activation & Performance
Activation time: 2 to 4 weeks (depending on water temperature)
Effective lifespan: Up to 3 months
After this period, the bundle must be removed and replaced
Ideal For
Garden ponds
Koi ponds
Ornamental water features
Seasonal algae prevention
Long-term pond maintenance programs
Coverage
50 g bundle treats up to 4,500 litres
Use multiple bundles for larger ponds
Installation Instructions
Calculate pond volume:
Length × Width × Average Depth (cm) ÷ 1000 = litres
Determine the number of bundles required based on pond size.
Float the Algae Straw in an area with strong water movement and oxygenation (e.g. near a waterfall or fountain).
Anchor the bundle in place to prevent it from sinking or drifting.
Ensure it remains floating and exposed to good circulation.
Usage Guidelines
Best introduced in early spring before algae blooms begin
Works best as a preventative treatment
Can be used throughout the year for continuous protection
Replace every 3 months
Important Information
Do not allow Algae Straw to sink and fully decompose in the pond
Do not use chemical algaecides while Algae Straw is present
If using algaecides, remove straw and place in a bucket of untreated pond water
Wait at least 2 weeks before reintroducing after chemical treatment
For best results, introduce new bundles 2–4 weeks before removing old ones
