CaribSea Super Naturals Crystal River 40lb

Product details

CaribSea Super Naturals Crystal River 40lb (00870) is a bag of pre-washed dry substrate (inert sand) from the Super Naturals line, intended for use in aquarium setups where you want a natural-looking riverbed look. Its practical value is that it’s designed not to affect pH or alkalinity, so you can adjust and manage key water parameters to match your tank and livestock needs. It can be used in marine aquariums when pH and alkalinity are properly maintained, and it’s also suitable for brackish aquariums when buffering is handled correctly. This substrate is sized to be friendly for soft-bellied fish and burrowers, supporting comfortable natural behaviors at the bottom of the tank.
