BEA Aequilibrium A is an advanced solution dedicated to the biological management of nutrients in marine aquariums . Presented in 10 openable capsules , this highly concentrated blend of nitrifying and denitrifying bacteria acts directly on the nitrogen compounds responsible for imbalances. It promotes long-term stability of the nitrogen cycle , limits ammonia and nitrite spikes, and helps reduce the accumulation of nitrates and unmetabolized organic matter. Ideal for starting a new tank, after medication treatment, or in cases of biological drift, it quickly colonizes rocks, substrates, and filter media. A reliable solution for maintaining a healthy, stable environment less susceptible to unwanted algae.

BEA Aequilibrium E is a concentrated , rapidly absorbed marine heterotrophic bacteria , specially formulated to optimize the biological management of nutrients in marine aquariums. Presented in 10 openable capsules , it acts directly on complex organic matter , nitrates (NO3) , and phosphates (PO4) , promoting their transformation into biomass that can be removed by skimming. Its broad-spectrum action targets both uneaten food proteins and planktonic lipids and polysaccharides from coral mucus. Ideal for bacterial proliferation strategies or carbon management, it helps to stabilize the system over the long term and limit problems such as algae blooms or persistent bacterial films.
BEA Aequilibrium Z is a concentrate designed to help marine aquariums regain a clean and stable state when organic matter accumulates. Its strength lies in a combination of enzymes and marine microbial consortia , enriched with oligosaccharides, trace elements , and metabolic stimulants, formulated to tackle the slimy layers and organic aggregates that eventually suffocate the aquarium decor and the system. With its 10 openable capsules , dosing remains simple, and the action aims to make organic compounds more digestible by bacterial biomass, and then exportable by the protein skimmer. The result: a cleaner, more stable tank, less prone to problems such as algae, bacterial films, or sludge.
BEA Aequilibrium PRO is an all-in-one booster for marine aquariums: a highly complex and extremely concentrated blend that combines autotrophic and heterotrophic bacteria , enzymes , trace elements , bacterial nutrients, and specific carbon sources . The goal is clear: to help the tank break down, metabolize, and export a wide variety of organic compounds, while promoting a more stable microbial balance. In practice, it is used when the system needs a real boost: after treatment, the use of oxidants, a change in methods, or when the aquarium becomes more susceptible to swarms such as cyanobacteria, dinoflagellates, or algae. Available in a 10-capsule format, with simple and adjustable dosing.
The standard dosage is 1 capsule per 500 to 1,000 liters of actual water. For smaller volumes, use ½ capsule per 100 to 500 liters . The goal is to adjust the quantity to the actual biological load of the system and the results of analyses.
For optimal application:
To maximize biological efficacy, the mixture can be left to stand for 6 to 12 hours at approximately 24°C , protected from light, before being introduced into the system. This step promotes the activation and initial multiplication of the strains.
In case of partial dilution, the remaining solution can be stored in the refrigerator for the next dose. As the capsules are sensitive to moisture, they must be tightly closed and stored carefully.
Standard program: 4 weeks of application followed by 1 week of rest . After the break, assess the parameters and decide on a new cycle if necessary.
Maturation (new container or transfer):
1 capsule / 500–1000 L or ½ capsule / 100–500 L weekly for 4 weeks. After a one-week break, the cycle can be repeated for longer maturation periods.
Resolution (medium/high nutrients, algae, bacterial films, detritus, low redox):
Follow the same dosage regimen for 4 weeks. If imbalances persist after the one-week break, repeat the protocol.
Maintenance (low nutrients, stable system):
Application follows the same ratio but is integrated into a reasoned management approach, always based on analysis. After the cycle, a one-week break is allowed before any possible resumption.
It is recommended to dose 24 to 48 hours after a water change . The product can be used in conjunction with BEA Aequilibrium E, Z, and PRO formulas for complete microbiological control.
The strength of BEA Aequilibrium A lies in the coexistence of complementary microbial groups . Nitrifying bacteria work in the oxygenated zones of the filter and rocks, while denitrifying bacteria act in the oxygen-poor micro-zones of the deep substrates or DSB. This dual action ensures a natural and gradual reduction of nitrogen compounds .
The product also helps to neutralize nitrite residues and unmetabolized organic compounds frequently observed in modern intensive systems.
BEA Aequilibrium A integrates perfectly into a comprehensive microbiological management system, particularly in combination with BEA Aequilibrium E, Z, and PRO . This combination broadens the spectrum of biological action and allows for even more balanced management of dissolved nutrients and organic matter.
Regular use promotes the development of a dense, active and stable microbial population , essential for maintaining a high-performing marine aquarium in the long term.
Keep capsules closed, in a cool, dry place . Handle promptly after opening to avoid exposure to moisture. Product intended for technical use in ornamental aquariums only . Contains no pathogens. Not intended for human or animal consumption.
The BEA Aequilibrium Kit brings together the entire AEQUILIBRIUM protocol in a single box: A + E + Z + PRO , comprising 40 ready-to-use, openable capsules . The idea is simple: to offer a comprehensive and synergistic approach to the biological management of nutrients and the maintenance of a stable microbial balance in marine aquariums. Marine microbial consortia, organo-mineral matrix, enzymes , trace elements , nutrients, metabolic stimulants, and specific carbon sources : everything is included to support nitrification, denitrification, and the transformation of organic waste. Used regularly, the kit helps the tank remain clean, stable, and less susceptible to problems such as cyanobacteria, dinoflagellates, algae, or sludge.
ZOA Bacter is a concentrate of non-pathogenic live bacteria fixed on a maerl substrate, designed to stabilize the biological balance in both saltwater and freshwater aquariums. Its multi-strain consortium naturally competes with unwanted algae, lowers nitrates and phosphates through assimilation, and transforms organic deposits into resources for filtration. Result: cleaner windows, clear water and a healthier biotope. Fish and corals regain vitality and resistance (protection against vibrioses), while a beneficial biofilm is established to feed certain invertebrates. Compatible with skimmers and filters, the effect is quickly seen, especially with correct mixing. 200 ml bottle (170 g) – 10 9 CFU/g , GMO-free, no risk of overdose .
