- Use a good dechlorinator before adding the new water to the tank. It's also a good idea to add liquid calcium to the water. This will aid in the development of the crayfish's exoskeleton, and will make the molting process go much more smoothly. I usually add 2-3 drops every other day for a 10 gallon tank.

There have been experiments performed by Ellis and Morris to observe how the pH effected oxygen consumption and uptake and metabolic activity in the Australian crayfish Cherax destructor.ethany Grant. Crayfish also called Crawfish or Crawdad, are crustaceans in which most of them live in freshwater and a few live in brackish or salt water. Some live in burrows on land close to a source of water, all crayfish have the ability to borrow (Hyman 1996).
