This may be a silly question but does reef crystals go bad? I was going to buy 2-3 boxes of salt which would take me quite a while to use. Just don’t want to buy all this salt and have it go bad
If you believe the vitamins in it are of utility, those will eventually degrade sitting in a bucket and faster once disoslved.
I personally see no demonstrated value to them.
Very long term, all salt mixes can get more and more precipitation of calcium carbonate. In general, if alk is still OK after the salt mix is settled and clear, the mix should be good enough to use.
