I have tried different systems to keep my peeler crab but the one I have now has to be the best, it keeps the water very clean and fresh. My system takes about 15 gallon to fill it up I don't change all the water very often if at all I just add 5 gallon every 4 or 5 days. Once you get the water at a nice temperature you will find that the crab come on much faster so you get them frozen down quickly. In the winter I use the tanks for keeping my yellow tails and, rag worm.
Here’s a list of what you need
Tanks
Heater
Water pump
Homemade external filter
Internal filter
Air pumps ,tubing ,air stones,
