Brightwell’s Alkalin8.3-P is part of a complete system for maintaining the major elements. The concentrated powder form is perfect for those who want to mix their own solutions at home for dosing by hand or with a dosing pump, and when coupled with CalcION-P and MagnesION-P, it is convenient and economical to maintain stable levels of each of these critical components.

Overview

• Alkalin8.3-P is a multi-component buffer that regulates pH, unlike sodium carbonate
• Supports stable aquarium chemistry
• Eliminates pH and KH instability caused by poor salt mixes and ineffective buffering products.
• Stronger and more economical than liquid calcium solutions; created for hobbyists maintaining large reef systems.
• Free of phosphates, silicate, and organic material.

Available in Two Sizes

• 500 grams
• 1000 grams

Instructions and Guidelines

Always try to maintain the alkalinity within a range of +/-1 dKH. Daily dosing maintains a more stable alkalinity and pH (and a more natural environment) than dosing weekly, in which the alkalinity spikes just after dosing and then gradually decreases throughout the course of the week.

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: Determine the alkalinity in the aquarium using an accurate test kit before supplementing.

Each gram of Alkalin8.3-P will increase the alkalinity in 1 US-gallon (3.785 L) of water by 12 dKH (or 4.2 meq/L).

Dosing Calculations

For dKH: Multiply tank capacity in gallons x dKH increase desired x .089 = grams of product to add. Example to raise the alkalinity by 1.2 dKH in a 50 gallon tank the calculation is: 1.2 x 50 x 0.089 = 5.35 grams or 1 teaspoon.

For meq/L: Multiply tank capacity in gallons x meq/L increase desired x .25 = grams of product to add. Example to raise the alkalinity by 0.5 meq/L in a 50 gallon tank the calculation is: 0.5 x 50 x 0.25 = 6.25 grams or 1.2 teaspoons.

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 skin, wash thoroughly with water. Keep out of reach of children. Not for human consumption.

Problem pH Aquariums:  Aquaria with low circulation at the water’s surface, or in which a CO2-injected calcium reactor is being employed, or which are placed in an enclosed room with human and animal inhabitants giving off CO2 into the air, often have a depressed pH due to carbon dioxide build up. Certain measures, such as providing outside air to the skimmer intake port or other methods to control CO2 can bring pH in the aquarium back into a higher desired range without raising alkalinity to an unacceptable level. Changes to pH should be made very gradually, again to avoid stressing aquarium inhabitants.
