Classic Substrate from Velda has been the standard for a biological substrate of your pond for many years. Owing to its very light and porous structure this substrate provides maximum adherence of micro-organisms.
An at top of that clear water guarantee!
Available in bags of 10, 20 and 35 litres.
To obtain a natural and stable balance in garden ponds, especially the substrate is playing a meaningful role. On the hand the substrate is important for the development of micro-organisms, on the other the material should contain a sufficient amount of nutrition to let the growth of pond plants proceed in an optimum and constant way. With this knowledge Velda has composed the pond substrate referred to. Consequently Classic Substrate from Velda has been leading for many years in the field of pond nutrient media. The substrate has an open structure and a large internal surface area. This guarantees maximum growth of micro-organisms. Besides, strong constant growth of water lilies and marsh plants is guaranteed by a sophisticated composition, including minerals and trace elements. Ponds sunk with Velda pond substrate obviously result in a quicker development and achievement of a biological balance and finally a clear water garden.
Advice for use: distribute a layer of about 2 cm of substrate over the soil. This can also be done in existing ponds. Simultaneous use of Bacterial nitrifying bacteria will prevent algal growth and provides a stable pond environment. If a new pond is sunk, it is recommended to treat tap water with Biofit. This makes the water fish-friendly and it also will prevent early algal growth.
