Info: Seachem VibrantSea® Dosing Instructions

1. Mix Vibrant Sea® with dechlorinated tap or purified water. We recommend the use of a commercial dechlorinator like Prime® to neutralize any tap water chlorine and/or chloramines. If source water quality is extremely poor we recommend purification with a Seachem Pinnacle™ RO/DI system.
   NOTE: To prepare small quantities, add 27 g of Vibrant Sea® per 1 liter of water for a specific gravity of 1.020. Add 31 g per 1 liter for 1.023. For larger quantities, use 1/2 cup per 6 L (1.58 US gallons) for a specific gravity of 1.020 or 1/2 cup per 5.25 L (1.38 US gallons) for 1.023.
2. Stir well until thoroughly dissolved. Vibrant Sea® is then ready for immediate use. Excessive mixing may result in cloudiness. Cloudiness will dissipate when the Vibrant Sea® solution is added to the aquarium.
3. Measure specific gravity. For reef aquarium 1.020 – 1.025 at 24°C (75°F) is recommended. NOTE: 540 g of Vibrant Sea® is formulated to create 20 liters of saltwater at a specific gravity of 1.020 and 620 g will create 20 liters at 1.023.
4. Adjust salt level accordingly. If specific gravity is too low, add more Vibrant Sea®. If too high, add more dechlorinated or purified water.
5. Change 20% of aquarium water every two weeks (or as necessary) to maintain optimum water quality.

Parameters at mixing	24°C (75°F)      sg 1.023
Water Volume	1 qt / 1 L	1 gal / 4 L	10 gal / 38 L	50 gal / 190 L
VibrantSea® Dose (g)	31 g	124 g	1180 g	5900 g

To calculate a dose of VibrantSea that is not on this table, here are the formulas:

The volume of water in Liters    x    (your target sg - 1)   x   1350  

=  The dose you will need in GRAMS

OR

The volume of water in Gallons    x    (your target sg - 1)   x   15.75  

=  The dose you will need in CUPS

__________________________________

Example: If you are dosing 33 gallons and want an sg of 1.025, your calculation would look like this: 

33  x  0.025  x  15.75  =  13 cups of VibrantSea®
