Boron
Boron
Boron (B) atomic number 5, PJS considers it to be a MAJOR element as it plays a crucial role in the skeletal, biological, photosynthesis, metabolism, coloration, growth and development of corals and is used by all other reef organisms and is above 1ppm in seawater. In the industry it is considered a trace element, we need to fix that. Boron belongs to the metalloid group, with silicon, I think they work together. Boron is highly reactive and forms compounds with many other elements in reef aquariums, it’s the biofilm, slime, ooze, glue. Boron is an essential major element for a healthy reef aquarium, impacting everything and the overall reef health. It’s crucial to maintain boron levels within the recommended range of 4–7 mg/l (ppm).
Boron Key Roles
Coral Skeleton Growth and Health:
A component for a strong skeletal structural calcification for hard corals and invertebrates.
Essential in the proper use and formation of aragonite, preventing the formation of brittle calcite.
Biological Processes:
Boron is part of the metabolic symbiotic process of corals and zooxanthellae for exchange, production of fluorescence, nutrient exchange and aiding in UV protection.
Enable production of defensive enzymes, crucial for preventing coral damage and promoting vibrant colors.
Enhanced Coral Coloration:
Boron plays a role in enhancing more vibrant yellow, orange and red colorations in corals.
Crucial in producing enzymes for photosynthesis, enhancing the vibrant fluorescent colors often seen in corals.
Protection Against Parasites:
Bromine is incorporated by corals stimulating the manufacturing of enzymes aiding in defense to protect coral tissue from predators and parasites.
Bromine at correct levels helps control the populations of harmful bacteria and algae.
Boron Levels
Natural Seawater Levels:
Bromine levels in natural seawater are typically 4.5 parts per million (ppm).
Target Aquarium Levels:
Many reef aquarists aim to maintain boron at natural seawater levels.
PJS recommends aim for a boron concentration of 4-7 mg/L.
Consumption Rate:
Slow to moderate.
Boron Testing
ALWAYS test boron levels in your reef aquarium before supplementing to determine if dosing is needed to avoid overdosing.
Testing:
Regularly test boron levels using a reliable test kit or by sending water samples for ICP testing
Boron Dosing
Start slowly by beginning with a low, gradual dose over many days avoiding any sudden shifts in water chemistry and monitor the effects.
Methods:
Boron can be dosed via liquid additives.
Consider Advanced Methods:
Dosing stock solutions with pumps and continuous drip systems can be used to maintain precise boron levels.
Considerations
Overdosing boron can become toxic to reef inhabitants. Overdosing boron will lead to undesirable algae overgrowth. Boron is used by everything at every level, so its presence is essential and critical for overall reef health. Low boron levels lead to coral bleaching, poor coloration, reduced tissue growth, and week skeletal structure. Boron is an important buffer for pH stability and essential for skeletal formation. Boron helps control the growth of certain algae that may have negative impacts to the reef environment. Boron is used at the cellular level in a reef environment. All corals and their zooxanthellae, invertebrates utilize boron, it is steadily consumed. Excess boron can impact alkalinity and pH balance. Boron and chromium work together. In corals bromine is used by both sides in the symbiotic relationship of corals and zooxanthellae. Boron levels along with proper levels of calcium, magnesium, potassium, and alkalinity must be maintained. Boron is essential for LPS and SPS coral growth and metabolisms.
