Finco Barley Straw

This natural algae control solution is designed for pond keepers and aquarists who want to reduce algae growth without using chemicals or treatments that may harm fish, plants, or beneficial organisms. It’s especially suited to ponds and natural water systems where long-term, eco-friendly algae management is preferred.

Key benefits
• Naturally controls and inhibits algae growth without chemicals
• Non-toxic, bio-friendly, and completely natural
• Safe for fish, plants, wildlife, and beneficial bacteria
• Works continuously once established
• Ideal for ponds and flowing or natural water systems

How to use it
Place the barley straw bag directly into an area of flowing water within the pond or system. Ensure it is fully submerged by weighing it down if necessary. Once in place, it will gradually begin working as it breaks down naturally. Algae control typically becomes noticeable within 1 to 3 weeks, and the straw remains effective for around 3 months before needing replacement.

Common problems it solves
• Persistent green water and filamentous algae in ponds
• Reliance on chemical algae treatments
• Algae returning quickly after manual removal
• Difficulty maintaining clear water in natural systems

Compatibility / warnings
Suitable for ponds and natural water systems only. For best results, ensure good water movement around the barley straw. This product does not kill existing algae instantly but works by inhibiting further growth over time. Do not use as a quick-fix solution where immediate results are required.
