Fresh Atlantic Ocean Seawater

This genuine marine saltwater provides the perfect foundation for aquariums, touch tanks, and marine life studies, replicating the natural environment found along Maine’s rocky coast.

Unlike synthetic salt mixes, our seawater contains live microorganisms and nutrients that promote biological balance and long-term tank health.

Tidepool Tim says,  “I would dare say that here in our part of Maine we have some of the cleanest, clearest, sea-water anywhere in the world. There are so few humans in this part of the state, we have little to no factories, few parking lots, sewer systems, or run-off. Pair that up with the flushing action of our extreme 20' tidal range and you can witness the churning, boiling, waters that ebb and flow in and out of the North Atlantic into our local bays each and every day. 

The old sow whirlpool is less than 3 miles from our offices. It's the largest whirlpool in the western hemisphere and it really mixes up the nutrients into the water column - no thermoclines here! Comes complete with a variety of planktonic organisms.  Use this water to fill your aquarium, for lab experiments, or touch tanks.”
