I live 1 mile from the beach... No more $48 buckets of salt. Yay! Bill
Exactly, why wouldn't you?
Natural sea water is what 99% of our fish were in a couple of weeks before we bought them. Artificial sea water is just what it is called, artificial. No matter how much you pay for it it will never have all the chemicals in it that real ocean water has.
Yes of course ASW is safe to use, I also use mostly ASW but only because I don't live right on the ocean, if I did I would never buy the stuff. In the 40+ years I have been adding NSW I have never seen a problem, my tank has never crashed, most of my fish are spawning, what kind of problems are people looking for?
I have not seen a paracite in decades and I am collecting in New York.
How many years do I have to use NY NSW before I consider it safe?
Do they test cancer drugs for 40 years?
All you need is a little common sense. The places where our fish come from are not exactly pristine, I have been to many of those places, many of them don't even have sewage treatment facilities.
Use ASW if you have to but there is nothing wrong with NSW.
Most of the problems people associate with NSW is bacteria. Bacteria may be bad for us but it is easily removed for fish tanks.
