Brightwell Aquatics Reef Code B - Balanced Calcium & Alkalinity System - Part B (Alk.) Information

The Brightwell Aquatics Reef Code B - Balanced Calcium and Alkalinity System - Part B (Alk.) Pet Store offers you an amazing supplement that can give your pets a substantial amount of calcium carbonate, providing them the trace elements they need to have strong bones and fins, as well as balance the alkalinity of their water. Easy and safe to administer, and very effective, this is one product you can’t be without if you want your pets to live long and healthy.

The product is made from a special formula containing a concentrated amount of calcium carbonate. It also contains other supplements that will meet your pet’s other needs. It does not have any harmful elements like phosphates, nitrates and silicates that can be lethal to marine life, and it uses no chemicals, additives and preservatives that can leave an awful taste and color in your tank water. It is a very effective solution, and just 5 ml can treat up to 25 gallons of water for a day.

So what are you waiting for? Get the Brightwell Aquatics Reef Code B - Balanced Calcium and Alkalinity System - Part B (Alk.) now! This item is available in 500 ml or 17 oz, and it comes in a bottle that has a long shelf life at room temperatures, keeping it from spoiling due to air, light and pests. It is also for sale in other amounts.

  • 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.
Technical Background
This method of calcium and carbonate supplementation is advantageous to hobbyists interested in a simple and effective solution to providing the very elements and molecules required for growth of reef-building organisms such as corals, clams, and their allies. Corals and other reef-building organisms require adequate and stable available calcium and alkalinity if they are to thrive, regardless of how perfect the remainder of their environment is. Under most conditions, the mineral that is secreted as skeletal material is known as Aragonite, composed mostly of carbonate and calcium by weight. Reef-building organisms must extract these substances from the surrounding water in order to secrete new skeletal material for growth. By maintaining the same ratio of calcium ions and carbonates in an aquarium as that found in natural seawater, these organisms have the necessary building blocks available in the proper proportions, even if the hobbyist chooses to maintain higher concentrations of these substances.
For maximum effectiveness of the Reef Code method, the magnesium concentration in reef aquaria should be adjusted to, and maintained between, 1,290 - 1,320 ppm before using these products (alone or together) or any other calcium and alkalinity products. Doing so helps prevent unwanted precipitation between calcium and carbonate ions. Additional information on this subject is available on our website and on the label for Brightwell Aquatics Magnesion.
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. Once the rate of alkalinity depletion in the aquarium has been determined, the proper dosing rate of this product can be easily calculated.

Instructions and Guidelines
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 Code 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 Code 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 Code 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 Code A and B to be required for obtaining and maintaini

Comments: I have used reef code part A&B for over a year with a auto dosing pump. I have found that I do not need to use as much as other products I have tried. My corals and fish seem very happy since I dose every 12 hr's and it maintains the ph and other parameters at a very consistent level.

Comments: I use this along with the Calcium and it is great! my corals have doubled in size and there color is beautiful. I was using ESV but this is a better product. I would highly recommend this product. Thanks Tonya

Comments: Obviously you use the A&B together. I have been able to keep the reef tank environment extremely stable using their products. I like the fact that even in the larger size the products come fully mixed and ready to go (I used the ESV and you had to dilute with RO water). I use a number of the Brightwell products and have found them to be fabulous. I am starting to use them exclusively when they have a product designed for the need. HIGHEST RECOMMENDATION
