- Pond substrate designed to be placed on top of soil
- Protects fish from uprooting plants
- Designed to work in tandem with Velda Plant Soil
The diameter of Velda's Pond Gravel is 4 to 6 mm and 12 to 16 mm. The gravel types of Velda are free from harmful substances and silicic acid, which makes it pre-eminently suitable for incorporation purposes in garden ponds.
Gravel is used to cover soil in plant baskets, it is also quite suitable, however, as cover material for marsh and pond soils. A soil which has been covered with gravel magnificently outlines a pond and permits a clear view of the fish.
