Storing Salt Water...

[jrobbins]

Here is my latest issue. I hate the whole production of mixing up w/c water. it means i have to keep a giant rubbermaid in the bedroom for a few days and it always causes problems. I was thinking that it might be easier to keep a smaller tub of saltwater (30gal.) mixed to a very high salinity *basically at saturation* hidden in the stand.

i would then just "cut" the super saturated solution with ro water to bring it down to .025 and dump it right it. This way I only have to have the big rubbermaid out for a few hours while it fills with ro.

Dumb idea or should i be fine?

I thought the calcium would precipitate if you tried saturation with salt mix & water.

saturation is the point right before precipitation...by definition if its saturated it wont precipitate out as far as i understand it...

i guess it would work but it seems like much more work than mixing a fresh batch of saltwater the day before a water change.

As I know it from my exp. only so much salt will disolve in a given amount of water. I do not know the ratio, but when I make a pickling brine and use too much salt,, some salt will not disolve until I add more water.

if i can have it premixed at a higher concentration i can have the rubbermaid in and out of the bedroom in about an hour (i just use DI and can make 50 gallons in about 2 hours), rather than having it sit around for two days while i let it age and futz with the salinity...

the theory is if i know the salinity of the water i have, and i know how many gallons of fresh water i have, its just math and a measuring cup to get things where i need to be...in my mind this seems like it would be much quicker than mixing up a fresh batch of sw each time...

j just tell her that's where it is going to stay from now on. Don't let her push you around anymore :lol2:

...lol. I guess I don't personally see the benefit, and you'll be risking having to match the salinity correctly on the second time around.. as well as risking precipitating..
