## Description

Product Description No matter what size your aquarium, Instant Ocean sea salts and water care products offer the smartest, easiest way to bring to ocean home. Our scientifically formulated sea salts are used exclusively by many of leading large-scale aquariums and research facilities across the country. Instant Ocean Sea Salt is the most carefully formulated and universally preferred sea salt in the world. The #1 choice of hobbyists, public aquariums, and scientific research facilities, Instant Ocean Sea Salt has set the industry standard for quality, consistency, and value for more than 50 years. Mix Instant Ocean with ordinary dechlorinated tap or purified water. NOTE: To prepare small quantities, use 1/2 cup of Instant Ocean per each U.S. gallon of water. Mix as directed. Stir vigorously to ensure a good mix. Although the Instant Ocean solution may be used immediately, we suggest aerating the water until it achieves oxygen/carbon dioxide equilibrium. Measure specific gravity with an Instant Ocean Hydrometer. Adjust salt level accordingly. If specific gravity is too low, add more Instant Ocean. lf too high, add more dechlorinated water. Change 20% of aquarium water every two weeks to maintain optimum water quality. NEVER mix salt in an aquarium containing animals. Recommended Specific Gravity Range - 1.020 - 1.024 at 77°F. Ingredients Free Of Nitrate And Phosphaste. No Special Additi Es.

Review: I used to own a tropical fish shop, a commercial FW fish breeder and now just a retired hobbyist. I only use Instant Ocean salts to hatch and/or grow Brine shrimp now. I have always obtained superior hatches using marine salt mixes over rock salt. In the past, I've cultured some corals but a true measure of a marine salt mix is to have reef fish breed in captivity. I have had pairs of Yellowtail Blue Damsels, Chrysiptera parasema) breed almost every week for months at a time in the early 1980's. In a different setup in the late 1980's and early 1990's I had a 125 gal reef tank. Mostly corals with a few fish. In that tank, my pair of Pygmy Flame Angelfish, Centropyge loricula and trio of Mandarin Dragonets, Synchiropus splendidus, would regularly spawn just after the lights turned off. Of course, I never successfully raised any young because that is too difficult if one is landlocked with no access to tropical plankton to fee the young but some have been successful in tropical Pacific and Caribbean ora.com facilities. Most major public and commercial marine aquariums use Instant Ocean because it has high predictable quality at reasonable prices.
Review: buen producto que se disuelve facil con una bomba de agua/wave maker, buena calidad , el paquete esta perfecto para una cambio de agua donde se requiera 5 o 10 galones. En mi caso lo dividi en 2 partes y fue justo lo que necesite a 35, fue muy acertado la concentracion. lo seguire comprando para mis cambios en el futuro.

## Questions & Answers

**Q: Why the crazy price hike?**
A: Crazy, I just ordered this 5 gal. bucket ( 160 gal ) and the price almost doubled ? Sooo, I drove a few miles to buy at Petco for about $40.00 w/tax, " Come on Man "

**Q: Can you use this for hermit crabs?**
A: Yes, you can use this to make drinking/soaking water for tropical land hermit crabs.  Just be sure they always have TWO WATER DISHES - one with de-chlorinated fresh water and one with brackish or salt water such as this.  The dishes need to be deep enough for them to fill their shells with water if they want, but must have sponge or some driftwood in them for easy access in and out.  Few people realize they need salt water as well as fresh, kudos to you for inquiring!  If you know which species you have, you should google to find out any specific quirks or requirements.

**Q: Ratio (ingredient weight to water volume) for brackish water condition?**
A: Typically, we recommend starting with 1/4 cup of salt to one gallon of water.  This is half the amount used to make full marine conditions.  You will need a hydrometer or refractometer to test the salinity.  You need 1.010 - 1.015.

**Q: If I have a 39 gallon tank, what size should I buy?**
A: You'll always need to make water for water changes so buying in bulk saves money. if you go to the web site it will tell you the exact amount per gallon
