Its just my personal opinion that you get what you pay for. I used Red Sea and then switched to Tropic Marin after my older brother enlightened me. Instant Ocean is as cheap as it gets. An investment like a shark tank to me would be a good reason to use the more expensive salt.
Tropic Marin mixes the clearest of all the salts as well and has more trace elements. Just an all together better way to go. But then again I like my fish to be taken care of the best I can as a responsible hobbyist.
It is a nice setup and personally i've never heard of nor seen a nurse shark bigger than 8 feet.
