The Original 2-Part Buffer System - 32 oz. of Component 1 (Alkalinity) & 32 oz. of Component 2 (Calcium)

Maintaining calcium and alkalinity levels shouldn't be complicated. Simplify with the original easy-to-use ionically balanced 2-part buffer system. It's an economical alternative to a calcium reactor, and when used in equal parts, the aquarist can easily maintain calcium and alkalinity levels with no mixing of powders, disruption of ionic balance, or addition of organic chemicals. In addition to supplying highly concentrated calcium and carbonate alkalinity required for calcification, B-Ionic Calcium Buffer System is also formulated to provide all other important major, minor, and trace elements in the proper ratios to duplicate the composition of synthetic seawater. As a result, B-Ionic Calcium Buffer System will help restore inorganic ions lost from protein skimming and help maintain the ionic balance of your aquarium water. 

Directions: The recommended starting dose is 1 ml. of each component per 4 gallons of aquarium capacity per day. Maintain alkalinity between 3.0 and 3.75 meq/liter (8.4 and 10.5 dKH) by testing daily and adjusting dose accordingly. Depending on the degree of calcification occurring in the aquarium, dose may have to be significantly increased over our recommended starting dose. Never add more than 1 ml. per gallon of each component in a 24 hour period, and never allow pH to rise above 8.45. Once the proper dose has been determined for your aquarium, testing can be performed less frequently. If your aquarium tends to run at a higher pH (over 8.45) we suggest you try our B-Ionic Calcium Bicarbonate System. When using kalkwasser in addition to B-Ionic Calcium Buffer System, follow the above procedure but start with 1 ml of each component per 8 gallons of aquarium capacity per day.

Component #1 - Carbonate Alkalinity: 2800 meq/liter (7840 dKH). 1 ml per gallon of aquarium water will raise alkalinity by 0.74 meq/liter (2.07 dKH).
Component #2 - Calcium Concentration: 54,000 ppm calcium ion. 1 ml per gallon of aquarium water will raise calcium concentration by 16ppm.
