Natural Coral Sand, Coral Gravel for Saltwater Aquariums, Layout, Interior Decor, 5kg

Natural Coral Sand, Coral Gravel for Marine Aquariums, Interior Use, etc. This is Okinawa sand with a particle size of approximately 1mm, available in a 3kg bag, suitable for aquarium layout materials and interior decoration.

Ideal for marine fish filtration tanks, crab and hermit crab tanks, interior decoration, layouts, and for keeping fish that prefer alkaline conditions.

When coral sand is added to an aquarium, minerals dissolve, maintaining a neutral to alkaline pH. This stabilizes water quality, making maintenance easier.
It also helps suppress bacteria and actively promotes the decomposition of ammonia nitrogen from fish waste.
Biological filtration encourages the growth of beneficial bacteria, creating a healthy environment.
For freshwater aquariums, it's a popular choice for the substrate of African cichlids and hermit crabs.
Guppies and platies prefer slightly alkaline conditions, so they are compatible with coral sand.
It is not recommended for killifish or goldfish in large quantities. If using for killifish or goldfish, a small amount is recommended.
Using it without washing can cause cloudiness in the aquarium water, so we recommend washing it before use.
