Instant Ocean Sea Salt (10 gal)

Great for fish only tanks. May be obvious to some but I learned the hard way that this salt doesn’t have nearly enough calcium or magnesium for a reef tank or to sustain coralline algae. Switch to reef crystals :)

Mixes up pretty quick doesn’t leave any chunks

The salt dissolved quickly as stated on the box. The reason I did not give five stars is the box was already open and the top was ripped open with part of the top not even all there. The salt is five stars, but I deducted one star which in my view is Amazons bad for shipping a box that was probably a return. fortunately, the salt was still sealed in the plastic bag that contained the salt.

Hi, did extensive research before deciding on Instant Ocean. It has all the correct amounts of minerals and trace elements. Best price by far. My fish have lived long and happy with this product. Highly recommend it. Please stay safe and healthy

Good price and accurate readings of specific gravity. Trace elements included, such as calcium.

I wanted something consistent and cheap for hatching brine shrimp. This product worked fine for my purpose. 1 tablespoon per litre and Im done. should last me at least a year before I need a refill. Feels slightly wet, but it doesnt affect my purpose.

I bought a bag for my saltwater tank. It works great and definitely serves its purpose. It was a great purchase.

I am happy with this product I will provoke never have to buy salt for my hermit crabs agin.

Excellent in every way. Negatives: pricey. Instructions are not very good. Experienced aquarists, however, will have no problems using it. Despite all that, it remains one of the best salts of its kind.

I have used instant ocean salt for years. It is always easy to use and consistant.
