Dymax Coloured Epoxy Gravel Blue

Create a colourful aquascape in your aquarium with Dymax Decorative Gravel. The gravel is epoxy-coated, which makes the gravel inert and prevents any adverse effects on water chemistry. Research shows that epoxy-coated gravel provides an optimum surface for the colonization of beneficial bacteria, which in turn provides biological filtration for clear and healthy water.
