Product details
Alkaline 8.3 – Brightwell is a KH (alkalinity) increasing buffer solution for marine aquariums. It’s designed to raise alkalinity and help support more stable pH by supplying carbonates, which are a key component of aragonite—the mineral reef-building organisms use as skeletal material. In practical terms, it can be used when your aquarium’s alkalinity needs replenishing to better support ongoing carbonate needs.
Features:
- Raises aquarium alkalinity (KH) using a carbonate-based buffer approach
- Helps increase pH stability by buffering pH rather than only changing it directly
- Provides carbonates, which make up the majority by weight of aragonite used for skeletal growth
- Continued dosing raises pH until 8.3 is reached; at that point pH remains unchanged while alkalinity continues to increase
- Free of phosphate, silicate, and organic material
- Formulated by a marine scientist
Specifications:
- Product type: Alkalinity (KH) buffer / carbonate solution
- Target pH behavior: pH buffering up to 8.3; pH remains unchanged while alkalinity increases
- Free of: Phosphate, silicate, and organic material
- Available sizes: 250 mL, 500 mL, 2 L
