Coral Essentials Coral Power Boron 50ml is a concentrated liquid boron additive
Boron Solution is a concentrated liquid boron additive, 50,000 ppm (mg/L). Boron in natural sea water is in the order of 4-5ppm. Boron is a component in the formation of coral skeletons, co-precipitating with calcium carbonate. Boron also assists slightly in pH buffering of aquarium water. For the advanced aquarist boron levels in marine tanks should be checked regularly to determine the take up in your system.
Calculate boron usage by testing regularly, then simply calculate dosing requirements to suit the depletion rate. Then continue a check of the levels every week or two.
Dosage rate: We recommend starting off dosing 1 drops/day for each 100L of tank water and increase steadily to 2 drops/day over a period of a month or so. Do not dose higher than 3 drops/day for each 100L of water for a heavily stocked system Manual Dosing Tables see picture
For the advanced aquarist, 0.1ml (2 drops) will raise the Boron levels by 0.05 ppm (mg/L) for each 100L of tank water. If you know the Boron depletion rate then dose accordingly Dosing By Usage.
