Drying NSW (a little)

[Paul B]

Now I am lucky to live 100 yards from clean Atlantic Ocean water so I have no need to buy it any more, but for most of my life I did.

Years ago there was a thought to collect salt water and dry it, then just add RO water to re constitute it.

It was found that that doesn't work because some of the elements combine to make other things (like Coca Cola) that will not support life.

But I wonder if you could dehydrate water to say 25% liquid and re constitute it to viable water.
After all sea water is still free and so is sunlight (to dry it) so the only expense would be shipping. But ASW also has to be shipped. Not as heavy of course.
And for the Sissies.......I mean the people who are afraid of parasites and diseases, I am pretty sure the drying would kill those although I am not positive.

Of course I am not even positive if I am awake now or in a coma. ;Bucktooth

I would imagine only Randy could answer this.

You’d have to prefilter out all living planktors and bac first or rehydration will bring stink and ammonia. For purified sw that’s a neat idea. I think many forms of bac can tolerate the changes but not all strains.

experiment! maybe they can tolerate a wider shift and nothing would die, rehydrate and sniff three days later lol easy test. reef life is pretty tough theyve got a chance

It may be that you are in the Matrix! ;Hilarious;Hilarious;Hilarious

Paul, have you ever taken a sample of that near shore water and had it tested? Just curious. I wouldn't use water here in SW Florida due to regular Red Tide blooms and beach closings due to raw sewage in the water.

Sort of on subject. I understand red tide concerns, but part of my day job is looking through a microscope so I know if that is an issue. As for human "stuff", we are lucky (?) that all of that goes into our bays that are separated by a line of barrier islands, so doesn't really affect my collection area. But to my question. Usually my near shore water comes in at 35 ppt. Over the past 18 months or so, salinity has come in any where between 24 and 31 ppt, so I end up having to add ASW mix to bring it up to 35. Maybe I should get me another big container and let it evaporate until 35. Would be kind of a pain, but I really don't like spending money making up water. And Paul, I don't think you are in a coma; it's just the way your brain is wired.

Ron I use 100% of the water from the shore here on Long Island NY and as you know, I don't have any problems, but the salinity is usually low so I have to add some ASW and the alk is about 6. I never tested the calcium right out of the sea but I normally add calc and alk anyway.

Of course the temperature now is about 38 or so so my corals always get the horrors when I collect because they aren't sure if I am going to warm it up first.

Someone actually posted once that they can't collect water up north because the water is to cold.
Like, is it me?

I collect it her right at the surf using a bilge pump. This day we probably shouldn't have been collecting but we are not Girly Men so lightning doesn't bother us.

Connecticut is across the Sound here about 27 miles away so it is basically the Atlantic ocean.
You can see the hose coming out of the water on the right. Right after this video, the sky opened up and we had to leave.
