Description

Brightwell Aquatics ALKALIN 8.3 is a concentrated KH buffer supplement designed specifically for marine fish and reef aquaria. This highly effective solution enhances alkalinity, stabilizing pH levels while providing essential carbonates that support the formation of aragonite, vital for reef-building organisms. With continued use, it raises pH up to 8.3 and increases alkalinity without altering the pH. Over 50% stronger than most competitors, ALKALIN 8.3 is free of phosphates, silicates, and organic materials, ensuring a clean, safe environment for aquatic life. Available in 250ml, 500ml, 1000ml, and 2000ml sizes.
