Instead of using two buckets for the transfer method, can I just buy 6 5 gallon buckets? I feel it's just easier for me instead of draining, cleaning and drying the buckets after 3 days. Can I just set up all 6 buckets with new saltwater, with a heater, thermometer, and air stones? Do I have to have air stones? Then after 72 hours in the first bucket, transfer my fish to the second bucket, then transfer to the third bucket after 72 hours, then transfer to the fourth bucket after 72 hours, then to the 5th bucket after 72 hours, then transfer to the 6th bucket after 72 hours, can I do this? Or do I have to use 2 buckets??? Is all need is heaters, thermometers, and maybe air stones? Do I really need air stones. Thank you
