Base Parameters
pH pH 7.91 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 1.00 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 15.00 ml of Reef Zlements Fluoride per day for 3 days.

Sr Strontium 7.44 mg/l 8 - 12 mg/l

Strontium is a macro element which is present in all reefs around the world.

Although its physiological effects are still being studied, there is evidence that it impacts on the health of animals.

Strontium is associated with calcification of coral skeleton and general coral health and is therefore important for maintaining good growth and coral health.

Strontium is a macro element that gets depleted from the water in our tanks reasonably quickly.

If adequate levels are not maintained growth and colouration (especially the blues) can be impacted.

Ensuring adequate levels of Strontium are maintained will lead to harder skeletons and more vibrant metallic colours.

Low concentrations of Strontium will lead to pale colours and brittle corals.

On a scale of 1-10 (1 low, 10 high) we classify the importance of Strontium supplementation a 7 and suitable for all levels of reefers.

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

To reach the desired level of 10.00 mg/l please dose 46.08 ml of Reef Zlements Strontium per day for 1 days.

Dosing Diary Total dosed 0.00 ml

Trace Element
Cr Chromium < LOD 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).

Co Cobalt < LOD 0.1 - 1 µg/l

Cobalt is a trace element present in a low concentration in oceans, varying between 0.002μg/L in north central Pacific Ocean and 0.39μg/L in Indian Ocean.

Cobalt is an integral part of vitamin B12 and plays a fundamental role in DNA; cell processes along being a nutrient for macro algae. It has been suggested that Cobalt might be a limiting factor of the bio-availability in the oceans and therefore an important trace element for the life of our animals.

Insufficient cobalt values reduce growth and colour formation.

Due to the extremely small amount needed in our aquariums, Cobalt is usually below the ICP detection limit. Nonetheless, despite potentially being present in undetectable levels the correction to reference levels will be ideal.

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

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

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

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).

I Iodine 24.26 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.

Fe Iron < LOD 0.2 - 5 µg/l

Iron is present in reefs all around the world, being one of the most important elements for all animals and plants in our aquariums. Having a strong role in many different metabolic processes, including the transport of oxygen in the blood of animals.

Iron gets depleted (precipitates) from the water in our tanks very quickly.

Iron has been known to have a positive impact in aquariums where macro algae is present and to improve green colours.

It also plays an important role in the availability of nitrogen.

A deficiency of Iron can result in corals and biofilms (bacteria) not being able to process nitrogen compounds as well, if at all.

The reflection of this is that nutrients (NO3 and PO4) in the system increase substantially.

Often Iron is a limiting factor in the nitrogen cycle and carbon dosing (CarboPlus) will not perform as expected in reducing PO₄³⁻ and NO3- due to a lack of Iron.

A good Iron supplementation will improve the green and yellow colours in corals.

Iron not only precipitates quickly but, is also removed by filtration and consumed quickly, it is recommended that the dose shown below is performed weekly by splitting in to as many doses as possible (ideally dosed more than once a day).

On a scale of 1-10 (1 low, 10 high) we classify the importance of Iron supplementation a 7 and suitable for all levels of reefers.

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

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

If you maintain macro algae please multiply your daily dose by 2x. However, if yellow corals do start to appear green, reduce the dose.

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).

For ease of dosing and if you wish you can dose our elements via a dosing pump mixing them together in 2 solutions.

Mn Manganese 0.76 µg/l 0.9 - 4 µg/l

Manganese is present in all reefs around the world, being an extremely important element for animals and plants in our aquariums.

Being a cofactor to many enzymes it has a strong role in the metabolic processes of almost all organisms, Manganese has been known to have a positive impact around the oxidative processes in organisms and is an essential element for corals having an impact in both growth and colouration (specially red).

Manganese in the aquarium precipitates quickly making it almost non-existent thus, can only be detected if the concentration is much higher than needed.

A lack of manganese is visible in dull tissue, reduced growth (or none at all), colourless growth tips and little to no polyp extension in Goniopora and Alveopora corals as well as light sensitivity in LPS.

Manganese also plays an important role in photosynthesis making it crucial for corals, algae and phytoplankton.

On a scale of 1-10 (1 low, 10 high) we classify the importance of manganese supplementation an 8 and suitable for all levels of reefers.

If GFO is used we recommend the additional supplementation of Manganese as GFO will absorb Mn.

PO43- Orthophosphate 26.00 µg/l 30 - 80 µg/l

Orthophosphate (PO₄³⁻) is likely the most important nutrient in the reef aquaria. When it comes to corals, too little can lead to coral starvation, and ultimately, death.

Orthophosphate deficiency can lead to coral brightening and poor polyp extension. If the levels are too low, corals can STN from the base, Acropora and Montipora can lose their colourful appearance and become beige, while others will become really pale.

If levels of PO₄³⁻ are maintained below 40 ug/l alkalinity should not be kept higher than 8dKH as STN/RTN will occur, starting at the tips (known as burnt tips). It is also important to keep Iodine below 80 ug/l if PO₄³⁻ is kept below 20-40 ug/l as SPS (mainly the Acropora genus) will tend to lose colour and brown out.

On the other hand, PO₄³⁻ swings can lead to STN/RTN, so it is important to carefully manage Phosphate levels.

To achieve ideal levels of coral growth, colouration, and health, PO₄³⁻ should be kept stable between 40-80 ug/l.

To achieve this, ensure that PO₄³⁻ is tested at least once a week at home, alongside your regular ICP testing.

Maintaining an adequate balance between Carbon, Nitrate and Phosphate is extremely important – ideally a ratio between NO3 and PO₄³⁻ of 1:100 is to be kept. You can achieve this using CarboPlus, NitroPlus and PhosPlus.

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

To increase PO₄³⁻ we recommend the use of PhosPlus in order to increase PO4 in a clean and controlled way.

To reach the desired level of 40.00 µg/l please dose 1.26 ml of Reef Zlements PhosPlus per day for 2 days.

Al Aluminium 32.568 µg/l 0 - 20 µg/l

Aluminium is normally found in seawater as an insoluble particulate material.

High levels of aluminium in the aquarium can be a result of aluminum based phosphate binding agents. Similarly, sources of Aluminium can be found in frozen food although at a lower concentration. Some salt brands, calcium reactor medias and zeolites based on minerals of the aluminium silicate group can also be a source of aluminium.

There are many known biological effects of aluminum, nearly all of which are negative and as no clear biological use in aquaria, nonetheless values < 20 µg/l can slightly enhance SPS corals colouration. However, with consistently high concentrations of aluminium corals will experience negative effects namely the decrease of soft tissue, low polyp extension and ultimately STN/RTN.

Soft corals like Sarcophyton, Sinularia and others when exposed to continuous high levels of aluminium will retract all the polyps and will start to die off starting at the base. Similar effects can be observed in mushrooms, zoanthids and GSP although after longer periods of exposure.

Aluminium can also bind to fish gills causing asphyxiation and death.

As such if aluminium phosphate absorbing are being employed we recommend these to be replaced by iron based PO4 biding agents.

At levels above 200 µg/l it is particularly important to locate and remove the source of aluminium in the tank.

To lower the concentration of aluminium we recommend the use of good quality GFO and or perform 6x 20% water changes with a high quality salt.
