- The carbonate-bearing component of a two-part method for dosing calcium and
carbonates (the substances largely responsible for increasing alkalinity
(”buffering capacity”)) in the same ratio as that found in natural seawater.
- Ionically balanced with respect to natural seawater concentrations of calcium and
carbonates when used in equal amounts with Reef Code A.
- Benefits reef-building organisms such as corals, clams, calcareous algae, etc.
- Simplifies calcium and alkalinity maintenance.
- Stronger than most competing products.
- Contains no phosphate, silicate, or organic material.
- Formulated by a marine scientist.
Basic: Shake product well before using. Add 5 ml (1 capful) of product per 25 US-gallons of aquarium water every other day or as needed to maintain the alkalinity within a range of 7 - 12 dKH. When used in this fashion, 250 ml treats up to 1,250 US-gallons (4,732 L). When used in equal amounts with Reef Cōde A, the calcium and carbonates being added are in the same ratio found in natural seawater. Do not mix products in the same container; this will cause the active components to precipitate and become ineffective. Allow 60 seconds to pass between dosing with Reef Cōde A and B.
Advanced: Determine the alkalinity in the aquarium using an accurate test kit before supplementing. Shake this product well before each use. Each ml of Brightwell Aquatics Reef Cōde B will increase the alkalinity in 1 US-gallon (3.785 L) of water by approximately 2.22 dKH (0.79 meq/L). If the initial alkalinity in the aquarium is below 7 dKH (2.5 meq/L), add this product at the maximum rate of 5 ml per 10 US-gallons daily until the desired alkalinity is attained, then dose daily or weekly as needed (see below). Note that each aquarium has different requirements for calcium and carbonates (which largely constitute Alkalinity or Buffering Capacity, hence pH-stability); therefore, it is not uncommon for unequal amounts of Reef Cōde A and B to be required for obtaining and maintaining the desired calcium concentration and alkalinity. To determine the daily dosing rate for alkalinity maintenance: estimate the volume of water in the entire aquarium system; divide the daily decrease in alkalinity by 2.22 (when measuring alkalinity by dKH; divide by 0.79 when measuring by meq/L); multiply this number by the volume of water in the system to get the daily dosage required (ml) to maintain stable alkalinity.
CAUTION: Contains carbonate and bicarbonate salts; harmful if swallowed. If swallowed: give water, get medical attention. May cause eye or skin irritation. If in eyes, flush with water for 15 minutes, get medical attention. If on the skin, wash thoroughly with water. Keep out of reach of children. Not for human consumption.
