Instructions

-
1
Buy marine salt. Do not use aquarium salt; save this salt for freshwater aquariums.
-
2
Mix two tablespoons of marine salt per gallon of water in your bucket to form brackish water particularly good for young fish. Add to your aquarium.
-
3
Add an extra tablespoon of salt per gallon every 6 months during cleaning and water changes. Eventually, put up to 7 tablespoons of salt per gallon. Stay at 7 tablespoons to mimic the natural migration of brackish water fish. These fish move closer to the salty seawater as they age.
-
4
Use a hydrometer to measure the gravity of the water; most fish like a gravity of 1.005 to 1.010. Research your particular species to see the most appropriate level.
-
5
Maintain your fish tank with weekly water changes. Occasionally stir the sand slightly to aerate it.
