I have marine fish and I use reef crystals salt for one tank and red sea coral pro for the other, salt tends to be a bit pricey, but you can get the 2kg bag of reef crystals and it will last you aggggggggges! Tells you how to make it up on the back, if they need true seawater salt levels, which is 1.025 specific gravity, I think its 33g per litre of water. Think you are supposed to use reverse osmosis water too, I know for marine fish you have to...so I assume crabs would be the same. To measure the salt water level, to make sure you have it right, you can buy a hydrometer or a refractometer (better).
