Brightwell Alkalin8.3 Powder Aquarium Buffer - 1000 Gram

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.

Instructions: Dissolve 2 grams (~1/2 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).
