Product details
Alkaline 8.3-P 1KG Brightwell is a powdered marine aquarium alkalinity supplement designed to raise alkalinity and help stabilize pH by using a multi-component automatic buffer. In practical terms, it supports reef aquariums that need consistent carbonate alkalinity by gradually buffering the system until pH reaches 8.3; after that point, pH is intended to remain unchanged while alkalinity continues to increase. This makes it useful when you want more predictable pH behavior than what can happen with poorly buffered additives or ineffective single-ingredient KH products.
Features:
- Raises alkalinity while acting as an automatic buffer to support pH stability
- Uses a multi-component powdered blend rather than a single KH source such as sodium carbonate
- Helps reduce pH and KH instability that can result from ineffective buffering products or poor salt mixes
- Continued addition raises pH until 8.3 is reached, then pH remains unchanged while alkalinity increases
- Supplies carbonates, which are the foundation of carbonate alkalinity and support the carbonate system in reef aquariums
- Formulated as a marine-scientist-developed buffering product
- Designed for testing-first use: determine aquarium alkalinity with an accurate test kit prior to supplementing
