Brightwell Potassium Concentrated Alkalinity Solution
Highly-effective alkalinity (KH)-increasing buffer solution designed to stabilize pH in aquariums by raising alkalinity levels. Provides a source of carbonates, which are a major component of aragonite—the mineral secreted by reef-building organisms as skeletal material.
Continued addition increases pH up to 8.3, after which pH remains stable while alkalinity continues to rise. This product is over 50% stronger than most competing alkalinity solutions. Free of phosphate, silicate, and organic materials. Formulated by a marine scientist.

FAQ
Can this product be used to raise pH above 8.3?
No. Once the pH reaches 8.3, it stabilizes and will not increase further. Alkalinity will continue to rise, but pH remains unchanged.
Is this product safe for reef tanks?
Yes. It is free of phosphate, silicate, and organic material, making it suitable for reef aquariums where water chemistry stability is critical.
How often should I add this solution?
Add according to your aquarium’s alkalinity needs. Monitor KH levels regularly and add gradually to avoid sudden changes in water chemistry.

I appreciate the strength of this alkalinity booster. It’s more effective than other products I’ve tried. I add it every 2-3 weeks depending on water testing. My tank’s pH stays consistent, which helps the corals grow better.

Great product for reef keepers who need reliable KH support. The formulation is clean and free of harmful additives. I’ve used it in a 120-gallon tank and it’s made a noticeable difference in water stability.
