A tip on purchasing Instant Ocean....
Instant Ocean is packaged in 2 ways: box and bag.
If you buy it in the box, you will get less salt for twice the price! Yep, you're actaually paying more for the package !
However, be careful when you buy in the bag...1. The bag is flimsy and if the seam breaks then your salt will spill out.
2. You need to make sure you really protect the unused portion of salt that comes in the bag [otherwise, moisture will make it clumpy].
