I was looking at those a while ago but did you really need to spend that much money on something you can do in like 30 seconds. I mean once you know how much salt goes in per bucket of water all you have to do is wait for it to mix. With consant stirring how long could that take. But what I was thinking why not get one of these babies for eal coral farming and fish breeding .
