Natural Seawater?

[pinhead]

If you live right on the water and could pump the water it might work. I'm a block away and water quality was not the problem. The novelty wore off after a few times of trying to fill up small containers, walk up to the car to fill a larger container and then drive home without loosing half your water as it sloshes around. Then repeat when you are moving the water into your tank.

It wash much easier to mix up my own water.
