Maintain stable alkalinity and support optimal pH with Nyos ION-B ALK/pH+, a concentrated, ready-to-use solution developed for modern reef aquariums. As a core component of the Nyos ION-B Method, this formula replenishes consumed alkalinity while helping maintain the stable water chemistry that corals need for healthy growth and coloration.
In addition to alkalinity support, ION-B ALK/pH+ contains sulfate, bromine, and fluorine to help maintain proper ionic balance over time. This balanced approach helps prevent long-term chemistry drift while supporting the natural biological processes that occur within thriving reef systems.
When used alongside Nyos ION-B CA/MG+, the complete ION-B Method replaces consumed alkalinity, calcium, and magnesium while helping stabilize pH between 8.0 and 8.3. The result is a simplified, highly effective dosing system that provides the essential building blocks for coral growth while reducing the complexity of reef supplementation.
