Hi all, I have the following containers up for grabs. They could potentially be used as saltwater mixing containers, or just to get relatively accurate water measurements, as they have both gallon and liter graduation marks. They're not fitted with bulkheads, but if you could add one, these continents would be a great addition to your mixing station. First come first served, but would prefer to hand them over at the frag swap this weekend. I have 3 of these 10 gallon containers. And I have one 12 gallon container.
