Maintaining balanced water chemistry is one of the greatest challenges for reef aquarists. Among the most important factors influencing coral health and growth are pH and carbon dioxide (CO₂) levels. When CO₂ levels rise, pH tends to drop, creating stress for sensitive corals and other invertebrates.

Managing phosphate (PO4) levels in a reef aquarium is one of the most important aspects of maintaining a healthy and thriving marine system. Excess phosphate can quickly lead to nuisance algae outbreaks, poor coral coloration, and even the decline of sensitive species like SPS corals and anemones.
