where to buy salt and sand?

[Ruth]

Do a search on here or elsewhere to see the recent issues that Kent has had with their Reef Crystals salt mix. Might make you re-think your decision. I think that the vast majority of people who use Instant Ocean are satisfied with it and it is by a long shot the most widely used salt in the industry. I don't use either brand but just thought I would at my 2 pennies.
