Brightwell Aquatics pH+ Alkalinity and pH Booster for Marine & Reef Aquariums Increases pH and KH Stability for Coral Growth and Enhances Carbonate Levels, 2L

Brightwell Aquatics pH+ is a high-purity, fast-acting pH booster designed specifically for marine and reef aquarium systems. Maintaining proper pH is essential to coral health and overall aquarium stability. This advanced formula raises pH and enhances alkalinity levels to support biological processes, including coral calcification and improved gas exchange. Ideal for systems with low surface circulation, calcium reactors, or CO2 buildup, pH+ helps return water chemistry to its optimal range of 8.1–8.5. By strengthening the carbonate buffer system, pH+ stabilizes daily pH fluctuations that naturally occur due to photosynthesis and respiration. It is especially useful in aquariums with refugiums, macroalgae, or heavy coral loads. Made with ultra-pure ingredients, pH+ contains no phosphate, nitrate, or unwanted substances and dissolves cleanly into solution. If your aquarium consistently tests below the ideal pH despite healthy alkalinity levels, use pH+ as part of your regular maintenance to keep conditions optimal for all marine life. For aquariums with very low pH or difficult-to-control conditions, Brightwell Boost pH+ may be used alongside pH+ for stronger response.
