After reading Calgaryflames thread and his outcome and also the outcome of gshock I was wondering if smaller rays have less of a tolerence than bigger rays to salt. I'm talking more about our usual 1-4 pounds per 100 gallon treatments. I'm not up to the same standard of biological knowledge that many of our members have but have learned alot from readng and trail and error. I've never salted a pup tank or a pregnant ray tank so I'm not sure if less salt is needed in these cases to have the same affect as say salting a 24" ray. Being smaller would thier bodies not be able to filter the salt out the same as a larger ray?
