Is it safe to switch up the salt you use in your tank?

[Kostas]

Is it a good thing to switch up the brand of salt you buy for your reef tank?

I’ve been using ‘instant ocean’ salt for years now… was down to one bucket and went to buy more and they were all sold out, so I got two buckets of ‘oceanic salt’.

Now should I mix a little from both buckets when I make up a bucket for a water change? Or just use it till its gone then go back to my regular stuff when it comes in

I think I recall reading about a horror story where someone switched salt brands and corals were dying in their tank due to that?
