Base Parameters
pH pH 7.82 8.1 - 8.4 mg/l

pH (potential of hydrogen) is a crucial parameter in a reef aquarium due to its significant impact on the overall health and well-being of the aquatic ecosystem, particularly for the delicate and sensitive organisms that inhabit a reef environment, such as corals, fish, and invertebrates.

Many reef-building corals and other calcifying organisms rely on the availability of calcium carbonate (CaCO3) to form their skeletons and structures. The rate of calcification is influenced by pH levels. Maintaining a stable and appropriate pH range ensures that corals have access to the necessary carbonate ions for efficient calcification.

pH plays a role in various biological processes, including enzyme activity, metabolic rates, and nutrient uptake. Organisms in a reef aquarium have evolved to function optimally within a specific pH range. Fluctuations in pH can disrupt these processes and lead to stress or even death of those organisms.

pH is closely tied to the balance between dissolved carbon dioxide (CO2), bicarbonate (HCO3-), and carbonate ions (CO32-) in the water. This carbonate equilibrium is essential for maintaining proper alkalinity levels. Alkalinity, in turn, helps stabilise pH by acting as a buffer, preventing rapid and harmful pH shifts.

pH affects the ability of water to hold dissolved gases, including oxygen (O2) and carbon dioxide (CO2). Proper gas exchange is crucial for respiration in fish and other organisms. If pH is too low or too high, it can disrupt gas exchange and lead to oxygen stress or suffocation.

pH influences the behavior and health of reef organisms. Fluctuations in pH can cause stress, alter feeding patterns, and lead to weakened immune systems, making organisms more susceptible to diseases.

Low pH in a reef aquarium can be problematic for several reasons, as it can adversely affect the health and well-being of the inhabitants and disrupt the delicate balance of the aquatic ecosystem.

Many reef-building corals rely on the availability of carbonate ions (CO32-) to build their skeletons and structures. Low pH levels can limit the availability of carbonate ions, hindering coral calcification and growth. This can lead to weakened and stunted coral growth, making the corals more vulnerable to environmental stressors and diseases.

Low pH often corresponds to reduced bicarbonate (HCO3-) and carbonate (CO32-) ion concentrations, which are crucial components of the carbonate equilibrium and alkalinity. Alkalinity is essential for stabilizing pH and preventing rapid fluctuations. Inadequate alkalinity due to low pH can lead to pH swings that stress the inhabitants.

Low pH can impact the ability of water to hold dissolved oxygen (O2) and release carbon dioxide (CO2). This can hinder proper respiration in fish and other aquatic organisms, potentially causing oxygen stress and suffocation.

Low pH can contribute to stress-induced coral bleaching. When corals are stressed due to factors like high temperatures or poor water quality (including low pH), they expel the symbiotic algae (zooxanthellae) that provide them with nutrients and color. This results in the loss of color and energy reserves in the corals, making them more susceptible to mortality.

Low pH levels can also potentially promote the growth of pathogens in a reef aquarium. Pathogens are microorganisms, such as bacteria, viruses, and fungi, that can cause diseases in aquatic organisms. When the pH of the water is too low, it can create conditions that are favorable for the proliferation of certain pathogens.

The microbial communities present in a reef aquarium play a crucial role in maintaining water quality and preventing the growth of harmful pathogens. Low pH can disrupt the balance of these microbial communities, potentially allowing harmful pathogens to gain a foothold and multiply.

Low pH can directly harm corals and other organisms. When corals are stressed by low pH, it can lead to tissue damage and openings in their protective layers. These openings can provide entry points for pathogens to infect the corals and cause diseases.

To increase pH in your tank consider dosing our unique 2 part dosing pHplus which not only will provide all the needed Macro and Trace elements but will increase the pH in the aquarium. If pHplus isn’t enough consider the use of CarboZorb in a CO2 scrubber – CarboZorb is our CO2 absorbing media which will remove the CO2 going into the tank and will contribute to a higher pH.

Macro Elements
F Fluoride 1.11 mg/l 1.2 - 1.9 mg/l

Fluor is a naturally occurring chemical element that is commonly found in water sources, including seawater in the form of Fluoride (F-).

Fluoride cannot be measured with an ICP technique and therefore requires a secondary test using Ion Chromatography or an Ion Selective Electrode.

It is an element that like Iodine and Bromide belongs to the halogen group and performs an important role. In a reef aquarium, fluoride is generally present at low concentrations as it is in marine environments.

The importance of fluoride in a reef aquarium lies in its potential role in coral health and skeletal formation. Some research suggests that fluoride may contribute to the structural integrity of coral skeletons by incorporating fluoride ions into the aragonite crystal lattice, which is the primary component of coral skeletons. This process is believed to increase the density and strength of the skeleton, making it more resistant to physical stress and predation.

However, it’s essential to note that while fluoride may have a beneficial impact on coral skeletons, it is just one of many factors that contribute to overall coral health and growth.

Fluoride levels are typically not a primary concern for most reef aquarium hobbyists however, values consistently below 1.2 mg/l will lead to poor colouration and growth, higher light sensitivity and less resistance to parasites.

On a scale of 1-10 (1 low, 10 high) we classify the importance of Fluoride supplementation a 6 and suitable for all levels of reefers.

To reach the desired level of 1.50 mg/l please dose 58.50 ml of Reef Zlements Fluoride per day for 2 days.

Trace Element
Ba Barium 7.14 µg/l 10 - 100 µg/l

Barium is an essential trace element present in reefs all around the world and plays a strong role in coral calcification supporting healthy coral growth.

Barium levels in seawater vary widely between oceans and depth. While it is found in concentrations ranging from 5 to 20 µg/l, it is agreed that a 10 µg/l level is an acceptable concentration level to maintain in the saltwater aquarium.

On a scale of 1-10 (1 low, 10 high) we classify the importance of Barium supplementation a 4 and suitable for all levels of reefers.

The use of our 2 part systems like Complete or pHplus will supplement Barium helping to maintain adequate levels over time.

Please note that for reference one drop is approximately 0.02-0.05 ml. If your recommended dose is below 1 drop per day, feel free to dose every other day (or less).

Cr Chromium 0.09 µg/l 0.2 - 1 µg/l

Chromium is a trace element present in small quantities in the seawater of reefs all around the world.

Chromium is used to form enzymes for fat metabolisation in cells as such may have positive impacts on coral skeleton calcification, health and coloration.

Chromium gets depleted from the water in our tanks quickly. Naturally, Chromium in seawater varies strongly and is usually between 0.2-0.6 µg/l.

Too low chromium values lead to slow growth. Chromium plays an important role in the absorption and use of fatty acids in corals.

On a scale of 1-10 (1 low, 10 high) we classify the importance of chromium supplementation a 4 and suitable for experienced reefers only.

The use of our 2 part systems like Complete or pHplus will supplement Chromium helping to maintain adequate levels over time.

It is recommended to dose Chromium continuously (as needed) in as many small doses as possible. This will ensure Chromium is present and available in the water (despite precipitation and potentially being below the ICP limit of detection).

I Iodine 25.15 µg/l 60 - 95 µg/l

Iodine is a trace element belonging to the halogen group, which is present in reefs all around the world, being one of the most important elements for all animals and plants in our aquariums.

It can be present in different organic and inorganic forms, however in our aquariums Iodine mainly exists as inorganic iodine, iodate, and iodide.

Nonetheless corals and bacteria can absorb all forms of iodine, and as such it is irrelevant in which form it is added.

Iodine concentrations in seawater vary widely, but it is commonly agreed that a level of 60-80 µg/l is ideal.

Iodine has been known to have a positive impact in aquariums where macro algae is present and to impact the blue and green colours of the genus Acropora and Montipora.

A low Iodine concentration manifests itself in poor colouration, reduced (or non-existent) growth, colourless growth tips or growth edges, and high light sensitivity allowing bleaching to more readily occur.

Low Iodine concentrations can also weaken the coral immune system, reducing any resistance to parasites.

Below ideal levels, Iodine will greatly impact bio-filtration and coral polyp extension is reduced (even when feeding LPS).

Very low levels of Iodine combined with low levels of other halogens such as Bromine can promote dinoflagellate growth.
With extreme iodine deficiency i.e. below 30 µg/l, SPS corals stop growing and RTN-STN infections occur more frequently.

With continued iodine deficiency, SPS corals start to STN from the base.

On a scale of 1-10 (1 low, 10 high) we classify the importance of Iodine supplementation a 9 and suitable for all levels of reefers.

The use of our 2 part systems like Complete or pHplus will supplement Iodine helping to maintain adequate levels over time.
