Blue Coloured Aquarium Sand (2kg)

Blue coloured aquarium sand is coated with aquarium-safe, non-toxic pigment that delivers a bold oceanic blue tone to the tank floor. The vibrant colouration is particularly effective in tropical fish display tanks, undersea-themed ornamental setups, and children's starter aquariums where visual impact is a priority.

The smooth, rounded grain is gentle on the barbels and fins of all bottom-dwelling species. The 2-kilogram bag provides approximately 30 × 20 cm of coverage at 2 cm depth, making it suitable as a complete nano tank substrate or as a coloured accent zone within a larger aquascape design. Blue and white sand can be combined in striped or swirled patterns for a unique artistic substrate presentation.
