Instant Ocean synthetic sea salt contains every necessary major, minor, and trace element and has no nitrates and no phosphates. It was developed through sophisticated biological and chemical testing, and every batch is analyzed to assure consistent high quality. Exceptional solubility, uniform particle size, and outstanding package value have made Instant Ocean salt the choice of aquarists for over 30 years. No other product out performs Instant Ocean salt.
I recently purchased a bag of this online and it showed up with not one but TWO holes in the bag. So you would think "okay maybe it was dropped during shipping or something". Nope! There was tape all over the bag!

I like this product, it is easy to use and dissolves fast.
