Has anyone ever recycled the salt when doing a water change? I've been thinking on how much does salt cost every time we do a water change, so I've been thinking there must be a way recycled assault I mean the water is the only thing that evaporates so if we could find a way to get the unwanted materials out of the changed water we will be left with just the salt. I wonder if running a protein skimmer we go out of bubble aeration would do the job? I would like to hear some suggestions from all of you.

I don't see how you would be able to remove the nitrates from what is left after evaporating out the water. Also those salt mixes contain trace elements that are needed in the water. I suppose you could find a way to add those back in a different way, but honestly, this isn't worth it. Buy the time you put in all this time and work it will just be easier to buy the salt

Yeah, I would be more interested in recovering the water... I always thought that at some point if the water sat long enough in the right conditions it would be safe to put back in the tank.. It would be nice to reuse the same water over and over again. But once you add the requirement to pump water into the mix.. then the cost of electricity makes it non-viable

But salt? Its super cheap... I buy it for a dollar for 10lbs.

Do what some sewerage facilities do, use plants to recycle sewage water back to drinking water[/QUOTE]

This salt is perfectly safe.. its food quality.. just didn't pay for all the certification testing to BE food quality. The bags that I buy do say its food quality. In other words.. probably more pure than what's sold for aquarium use. Been using it for over a decade..

If it says its 100% salt I wouldn't worry too much about quality.. just make sure there are not additives or de-caking agents added. I have seen 3 different brands come through my pool supply place I go to and so far its always been pure.

Tank i have now is about 1700 gallons.

I think some people here are talking about marine aquariums and others freshwater aquariums with a little salt made for freshwater aquariums.
