Real Ocean Water is natural sea water that's already filtered, sanitized, and pH balanced.
No mixing. No measuring. No adjusting. Just pour Real Ocean Water directly into your aquarium. It's the easy way to maintain salt water fish.
Catalina Water Company has been providing natural sea water to pet stores since 1988. During that time, thousands of salt water aquariums slowly switched from synthetics to natural sea water. The results are healthier marine life and cleaner, clearer water. Now, you can have natural sea water delivered right to your door. It arrives ready-to-use in a sealed bag inside a protective box.
Phosphate free. Nitrate free. pH balanced at 8.3.

Instructions For Use
Monthly Maintenance and Water Changes: Remove 25% of the water from your aquarium. Replace that amount by pouring Real Ocean water directly from the container into your aquarium.
Filling Your Entire Aquarium With Real Ocean Water: Rinse and fill your aquarium with Real Ocean Water. Once optimum temperature is reached, transfer fish and marine organisms into your aquarium.
Helpful Hints
It is recommended that when changing more than 25% of aquarium water, pour Real Ocean water into your tank through a strainer from a height of at least 18 inches. This allows the water to aerate, increasing the amount of oxygen in the water.
Water temperature is important.
The temperature of the aquarium must be the same as the temperature of water from which fish are transferred. During monthly water changes, ensure that Real Ocean water is within 4°F of your aquarium.
To adjust temperature of Real Ocean water, simply place unopened boxes of water in a room that is of similar temperature to your aquarium for several hours prior to use. Additionally, you can carefully remove the bag of water and place it in a bathtub filled with water that is the same temperature as your aquarium.
