Tropic Marin BIO-ACTIF

Contains Naturally Occurring Marine Biopolymers

Tropic Marin Bio-Actif Salt mix has been professionally designed to be used in reef tanks that employ some type of carbon dosing to create an Ultra-Low Nutrient System (UNLS). The unique salt incorporates bio-active marine agents that help protect and enhance your aquarium's fauna growth, leading to more vibrant and healthier corals. Healthy corals will naturally grow faster and are more robust, but Bio-Actif salt is great for fish too by increasing the protection against damage to mucous membranes, heightened sensitivity, and elevated mating activity.

Instructions:

We suggest starting with 0.5 Cups of Tropic Marin Bio-Actif Salt per 1 Gallon of RODI water. For the best results, the water should be circulating and at a temperature of 73-77 °F. Once the water is up to temperature and circulating, slowly adding the appropriate amount of salt will allow it to fully dissolve quickly without creating any concentrated areas where precipitation may occur. The freshly mixed solution may be slightly cloudy but will clear once it is added to the tank.

Important - Using conductivity with freshly mixed Bio-Actif saltwater will show about 10% low. It is recommended to use specific gravity for reading Tropic Marin Bio-Actif Salt. 

When you have added almost all of the salt and the mixture is fully dissolved, start measuring the specific gravity with a refractometer or similar instrument. Keep adding small amounts of salt until the specific gravity is the value you desire. The specific gravity of the sea salt solution should range from 1.025 to 1.027 (at 73-77 °F / 23-25 °C) and the pH -value should be in the range of 8.0 – 8.4. If all parameters are correct, the salt water is ready to use.

Note: Slight cloudiness is normal at this stage and indicates that the bio-active substances are taking effect. Not recommended for Auto Water Change systems since after a couple days a film will develop on the reservoir.
