Carbonate is an essential component in the formation of calcium carbonate skeletons, i.e. coral growth. The kh level in marine tanks need to be checked regularly to determine the carbonate uptake in your system.
How much carbonate being used can be calculated by testing at regular intervals to see how much the KH level drops during the set interval. Then it is simple to calculate dosing requirements to suit the depletion rate. You can mix your KH solution by following the simple how to mix bluetang dosing salts guide.
Your tank will change over time as coral grows, new pieces are added as well as invertebrates that also take up carbonate. Blue Tang have found ideal KH levels to be at about 8-9 dKH for most aquariums.
The bluetang range of products perfectly compliments the Coral Essentials range!
