Coral Essentials, Coral Power Nitrate Up is a concentrated, inorganic nitrogen source (50,000 ppm). In bacteria driven systems it provides an essential nutrient source to assist in biologically balancing marine aquarium systems.

Benefits of dosing nitrate (NO3–) in a marine aquarium.

Prevents complete nutrient starvation - Very low/zero nitrate can starve zooxanthellae and macroalgae, reducing coral growth and coloration; small background NO3 supports normal primary production.

Supports coral and zooxanthellae physiology - Moderate nitrate levels provide nitrogen for symbiotic algae and host tissues—helpful for protein synthesis, growth, and recovery after stress.

Stabilizes algal nutrient balance - Adequate nitrate (relative to phosphate) can reduce opportunistic uptake of other micronutrients by nuisance algae and help prevent them from scrounging limiting resources that corals need.

Improves coral pigmentation and tissue health (in some cases) - Low but non-zero nitrate often correlates with better color and polyp extension versus absolute zero; many reef keepers target small amounts to optimize appearance and growth.

Helps refugium/refuge productivity - Nitrate supports macroalgae and phytoplankton growth in refugia/refugiums used for nutrient export and food production.

Reduces stress from rapid nutrient shifts - Maintaining a stable, modest nitrate concentration avoids large swings that can stress livestock and encourage nuisance blooms when suddenly fed or dosed.

Coral Essentials guidance and typical reef targets: ~1-5 ppm NO3 (many SPS-focused systems aim 0.5–3 ppm; mixed reefs often 1–5 ppm). Soft‑coral and macroalgae-heavy systems tolerate higher.

Available in 100ml.

Manual Dosing - Only for ULNS systems we recommend starting off dosing 1 drop (0.05ml)/day for each 100L (26 gals) of tank water.

Advanced Dosing - For the advanced aquarist 1ml will raise the nitrate levels by 0.5ppm (mg/L) for each 100L (26 gals) of tank water.

Coral Essentials, Coral Power Phosphate Up is a balanced, inorganic phosphorous source (1,000 ppm). The phosphate based nutrient source, along with naturally occurring bacteria, provide the right environment to ensure the uptake of excess dissolved organics.In ULNS (Ultra Low Nutrient Systems) aquariums corals can have poor colouration and unhealthy if they are starved of available phosphate.

Benefits of dosing phosphate (PO4³–) in a marine aquarium.

Prevents nutrient starvation - Very low or zero phosphate can limit growth of zooxanthellae and macroalgae, reducing coral growth, tissue repair and coloration. A small background PO4 supports normal biological processes.

Supports primary production and refugia - Phosphate is an essential nutrient for macroalgae, phytoplankton and microbes in refugia; adequate PO4 promotes refugium productivity and nutrient export.

Balances nutrient ratios - Maintaining some phosphate (with nitrate) helps keep nitrogen:phosphorus ratios in a range that discourages opportunistic uptake of trace elements by nuisance algae and supports balanced coral symbiont nutrition.

Reduces risk of sudden nutrient swings - Maintaining a low, stable phosphate level avoids big fluctuations that stress livestock or trigger nuisance blooms when conditions change.

Aids normal growth and metabolic processes - Phosphate is vital for ATP, nucleic acids and cellular metabolism across all organisms — tiny amounts are required for tissue growth and repair.

Coral Essentials guidance and typical reef targets. Mmany reefkeepers aim for ~0.02–0.10 ppm PO4. SPS-heavy systems often target lower (0.01–0.03 ppm) while mixed reefs and systems prioritizing macroalgae/refugium growth may tolerate higher (0.05–0.10 ppm).

Available in 100ml.

Manual Dosing - We recommend starting off dosing 1 drop (0.05ml)/day for each 100L (26 gals) of tank water.

Advanced Dosing - For the advanced aquarist 1ml will raise the phosphate levels by 0.01ppm (mg/L) for each 100L (26 gals) of tank water.

Using carbon in a marine aquarium provides several important benefits related to water quality and overall tank health. Here are the main advantages:

Chemical Filtration - Activated carbon adsorbs impurities, toxins, dissolved organics, and pollutants, helping to keep the water clear and clean.

Removes Organic Compounds - Carbon effectively reduces dissolved organic compounds that can cause coloration, odors, or reduce light pe*******on, promoting crystal-clear water.

Improves Water Clarity - By removing tannins, discoloration, and particulate matter, carbon enhances the visual clarity of the aquarium.

Reduces Harmful Substances - It can help remove medications, dyes, and other chemical residues after treatments or disturbances.

Prevents Algae Growth - Removing organic nutrients and compounds can help reduce algae proliferation caused by excess nutrients or dissolved organics.

Activated carbon needs to be replaced regularly (every 4-6 weeks) to maintain its effectiveness. Carbon primarily handles chemical filtration; it should complement biological and mechanical filtration methods. Proper water flow through the carbon media is important to maximize its adsorption capacity.

Our Coral Essentials Activated Carbon is an ultra-high grade, bituminous carbon, in a handy 2L bucket. It is a virgin activated carbon in pelletised form, typical size 4-5mm diameter and 6-7mm long. Derived from bituminous coal, its high activity and extreme surface area (due to the activation manufacturing process) make it ideal for marine aquarium filtration applications. For filters, it’s generally accepted that carbon made from bituminous coal is far and away much superior. In fact, it’s the first choice for human drinking water purifiers the world over.

Rinse carbon thoroughly in fresh water before use to remove any residual carbon dust.
​
Usage instructions:
Low Filtration—Place 50ml in a reactor or filter bag for each 100L of aquarium water
Med Filtration—Place 100ml in a reactor or filter bag for each 100L of aquarium water
High Filtration—Place 150ml in a reactor or filter bag for each 100L of aquarium water
