Velda Superdensa 10Ltr (oxygenator substrate)
Oxygenating plants in your pond tend to need a lot of nutrients, and you can provide that with Velda Superdensa 10Ltr (oxygenator substrate), perfect for ensuring your pond produces good levels of natural oxygen for your fish.
Product Information
Velda's Superdensa substrate is a planting substrate for submerged oxygenating aquatic plants.
Light and porous, Superdensa provides the perfect medium for plants such as waterlilies and rununculus, ensuring the roots remain anchored and stable. Oxygenating plants are a natural way to ensure that your pond has stable levels of oxygen, so using a good soil will ensure good, strong growth.
We recommend lining plant baskets with hessian lining and then adding soil. This gives the plants a firm base and still allows nutrients to the roots.

We brought this product as we are experimenting with floating baskets in our Koi pond and until this my husband was concerned with water clarity as most substrate is made for sinking baskets an has an element of nutrients making him fret about clarity and water quality. with floating baskets this substrate so for seems to be the bees knees and clarity appears to be returning, the substrate is quite light (in comparison with other brands) the Koi love the baskets rummaging underneath and nibbling roots etc and hiding when they choose. -
