Brightwell Aquatics Alkalin8.3-P 500 grams

  • $ 16.99

KH Buffer Powder for all Marine Fish and Reef Aquaria.

  • Highly-effective alkalinity-increasing (”buffer”) powdered blend.
  • Helps increase pH stability in an aquarium by raising the alkalinity; continued addition raises pH until 8.3 is reached, at which point the pH remains unchanged and the alkalinity alone increases.
  • Provides a source of carbonates, which make up the majority by weight of aragonite, the mineral secreted by reef-building organisms as skeletal material.
  • Formulated by a marine scientist.
  • Determine alkalinity in aquarium with an accurate test kit prior to supplementing. Do not add this product directly to an aquarium without first diluting in water as directed.
Technical Background:
Alkalinity, also referred to as carbonate hardness or buffering capacity, is essentially a means of quantifying the stability of pH in a solution, such as aquarium water. In an aquarium, weak acids formed by oxygen respiration and the decomposition of organic material gradually deplete alkalinity. If left unchecked, the alkalinity drops below a critical level and pH begins to fluctuate more wildly than is normally suggested (a daily pH shift of +/-0.2 is normal in marine aquaria), causing stress to livestock. Alkalinity is also depleted by reef-building organisms during the production of aragonite (~60% carbonates by weight), and is therefore very important for their rapid growth. Maintaining the alkalinity in marine aquaria between 7 - 12 dKH (2.5 - 4.3 meq/L) will generally maintain pH within the desired range.

Instructions and Guidelines:
Basic: Dissolve 2 grams (~½ teaspoon) of product per 20 US-gallons of aquarium water in 8-fl. oz. of fresh water; add every other day or as needed to maintain the alkalinity within a range of 7 - 12 dKH. When used in this fashion, 1,000 g treats up to 10,000 US-gallons (37,854 L).

Advanced: Create a stock solution by dissolving 20 grams (~5 teaspoons) of Alkalin8.3-P in 8-fl. oz. of fresh water (preferably purified); each ml of the solution will increase the alkalinity in 1 US-gallon (3.785 L) of water by 0.36 dKH (0.13 meq/L). [Reference: Each g of Alkalin8.3-P will increase the alkalinity in 1 US-gallon (3.785 L) of water by 6.8 dKH (2.5 meq/L).] If initial alkalinity in the aquarium is below 7 dKH (2.5 meq/L), add the stock sol’n at the maximum rate of 10 ml per 20 US-gallons daily until desired alkalinity is attained, then dose daily or weekly as needed (see below). Maintain the alkalinity within a range of +/-1 dKH. Once the desired alkalinity has been acquired, measure the alkalinity at the same time each day over a one- to two-week period to determine required dosing rate. To determine the daily dosing rate (preferable to weekly dosing): estimate the volume of water in the entire aquarium system; divide the daily decrease in alkalinity by 0.36 when measuring dKH or by 0.13 when measuring meq/L; multiply this number by the volume of water (gallons) in the system to get the daily ml of stock sol’n required to maintain stable alkalinity.
