Consider using river sand for crabitat.
Unfortunately, in Korea I can't buy commonly used playsand.
Instead, I can get washed river sand or sea sand.
This sand is sand that has been cleaned of impurities and gravel and washed with water.
This sand is used for play, gardening and construction purposes, but I don't know if this sand is safe for crabs.
Is it safe to use this sand?
If sand is used, how long can the substrate be used without deep clean?
I am waiting for a reply. Thank you.
