They’re not familiar with that either. So the aquatic veterinary medicine world was way behind zoo and terrestrial animal at that time. And then I just have to share with you the salt water, we would make it up, we had a reservoir of a hundred thousand gallons. So you fill the reservoir, the a hundred thousand gallons of fresh water. And then I think, think at the time the recipe called for, it was probably 20 some different salts that had to be poured into this mixing reservoir about probably a four foot cube and maybe two or three feet deep. And as you poured in the salt, there was turbulence and would help dissolve the salts and they would eventually spill over into the reservoir. The, the major component of our salt water and of ocean water for that matter is sodium chloride, table salt. It went into the tune of 23,000 pounds put in by probably 50 pound sacks.
