Coralline Accelerator – Nutrients for Coralline Algae Growth in Marine & Reef Aquariums – 500ML

Brightwell Aquatic`s Coralline Accelerator provides crucial elements and molecules necessary for the growth of coralline algae, corals, clams, and similar invertebrates. The active components of Coralline Accelerator are provided by a combination of sources including natural aragonite, which increases the solubility and effectiveness of the solution. 


  • Complete source of the elements and molecules that are directly used by coralline algae, corals, clams, mollusks, snails, tube worms, and more
  • Provides calcium, strontium, magnesium, and potassium in approximately the same ratios in which they occur in aragonite.
  • Very strong source of carbonates (derived from aragonite), the other important group of ions involved in aragonite formation.
  • Increases alkalinity to help stabilize pH.
  • Stronger than competing products.
  • May be used as an inexpensive alternative to automated calcium reactor systems with similar results
  • Free of phosphate, silicate, and organic material.

Instructions & Guidelines:


  • Shake product well before using.
  • Add 10 ml (2 capfuls) of product per 50 US-gallons of aquarium water every other day or as needed to maintain the calcium concentration within a range of 412 – 450 ppm. When used in this fashion, 500 ml treats up to 2,500 US-gallons (9,450 L). 
  • Coralline Accelerator may temporarily cloud aquarium water after addition, therefore it is recommended that the product be dosed in the late evening.

  • Determine the calcium concentration in the aquarium using an accurate test kit before supplementing. 
  • Shake product well before using.
  • Each ml of Coralline Accelerator will increase the concentration of calcium (?[Ca2+]?) in 1 US-gallon (3.785 L) of water by approximately 20 ppm.
  • If the initial [Ca2+] in the aquarium is below 412 ppm, add this product at the maximum rate of 20 ml per 30 US-gallons daily until the desired calcium concentration is attained, then dose daily or weekly as needed (see below).
  • Always try to maintain the [Ca2+] within a range of +/-10 ppm.
EZ Calculations:

  • Multiply tank capacity in gallons x ppm increase desired x .05047 = ml of product to add.
    • For Example: to raise the concentration of calcium in a 50 gallon aquarium by 2 ppm, the calculation is: 50 x 2 x .05047 = 5.047 ml or about one capful. (a capful is 5 ml).

Note: Target ion-specific supplementation may be called for in some aquaria, depending upon stocking density of reef-building organisms and environmental conditions within the system. Additionally, hobbyists may choose to use Coralline Accelerator in conjunction with other methods of calcium, strontium, magnesium, and carbonate supplementation as a means of diversifying their dosing routine. The rate at which calcium and carbonates are extracted from the water is determined by the stocking density of reef-building livestock, type of lighting, and other conditions; therefore, each aquarium will have different requirements for the rate of supplementation.
