20kg bag of silica sand natural in colour. This is a great way to brighten up your aquarium and is suitable for tropical, Coldwater and marine fish aquariums.
This sand is far cleaner than gravel and will not alter the ph level of the water in your aquarium.
Give the sand a light rinse prior to putting it in your tank. Although the sand is very clean we like to be safe.
Superb for catfish and loaches also the white sand makes goldfish and koi more visible when used in ponds.
