Velda Pond Gravel 4–6mm is specially selected for safe use in garden ponds and water features. Unlike ordinary gravel, this high-quality aquatic gravel is free from harmful substances and silicic acid that can trigger unwanted algae growth. This makes it ideal for maintaining a clean, healthy pond environment. Designed primarily to prevent soil from flushing away, pond gravel is perfect for covering planting baskets and stabilising pond soil around aquatic plants. It also works effectively as a decorative cover for marsh and pond soils, helping to clearly outline your pond while allowing an unobstructed view of fish. The natural 4–6mm grain size provides excellent stability without compacting, ensuring water can circulate freely around plant roots. For best results, use with Velda Pond Soil, add nutrient tablets near roots, moisten and press soil firmly, then cover with a 2–3cm layer of pond gravel. Ideal for outdoor ponds of all sizes, this durable gravel supports plant growth while preserving water clarity and balance.
