OceanMax dark blue aquarium gravel is a coloured substrate of consistent 3–5mm stones, sold in a 1kg quantity for freshwater fish tanks. The deep blue base gives aquariums a striking, cool-toned look and lays neatly around plants and decorations.

The dark blue contrasts well with orange, red and yellow fish and green plants, so the whole display comes to life.

Good to know:
– Grain size: 3–5mm — a consistent mid-size that is easy to spread
– Quantity: 1kg — suits the base of a small or medium fish tank
– For freshwater aquariums; works in planted and decorative layouts
– Rinse before laying to clear dust and keep the water clear
