Our Coral Essentials Bromide Solution is a liquid Sodium Bromide additive at 50000 ppm. Bromine in natural sea water is in the order of 65ppm. For the advanced aquarist bromide levels in marine tanks may be checked regularly to determine the take up in your system.

Dosage rate: We recommend starting off dosing 1 drop (0.05ml)/day for each 100L of tank water and increase steadily to 2 drops (0.1ml)/day over a period of a month or so. Do not dose higher than 3 drops (0.15ml)/day for each 100L of water in a heavily stocked system.

For the advanced aquarist, 0.1ml (2 drops) will raise the Bromine level by 0.05ppm for each 100L of water.
