Dymax Cosmetic Sand 4kg (DM523) Substrate for aquascaping and landscaping Features: Dymax Calcite Sand is an ideal substrate for bottom dweller fish, corydoras and shrimps. • Natural sand from mountains, streams and rivers • pH value neutral • Wash carefully before use Sand substrates are great for fish only aquariums, serving the purpose of providing a surface for the beneficial bacteria to build colonies. With todays filter technology, the size of the gravel does not really matter, but it is recommended to use a finer gravel if bottom feeders are home in the tank. The substrate should be about 5-6.5cm in height (or depth) in the base of the tank (which is roughly 4kg of substrate for approximately 380 square centimeters of tank surface).
