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 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 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.
When a reef aquarium starts to develop a slimy film or accumulate deposits that stick to rocks, filter media, or sand, the system quickly loses its effectiveness. BEA Aequilibrium Z was designed precisely for these situations: its formulation promotes the breakdown of mucilage and the fragmentation of organic aggregates from various sources. These viscous layers, whether predominantly bacterial or algal, can trap nutrients, slow down nutrient exchange, and weaken sensitive organisms. Here, the product acts as a biological "helping hand": it helps to recirculate organic matter in a more manageable form.
The key point is the enzymatic process: enzymes help break down complex organic molecules into simpler elements. This allows the microbial communities in the tank to assimilate them more easily, improving natural removal, especially through the protein skimmer. The goal isn't to mask the problem, but to facilitate a return to cleaner and more consistent organic management.
BEA Aequilibrium Z combines enzymes , oligosaccharides , targeted nutrients, and fast-metabolizing heterotrophic bacteria . This blend was designed to accelerate the transformation of what accumulates in a modern aquarium: organic waste, particles, mucus, fine sludge, etc. The product releases carbon and nutrients in more accessible forms, promoting more efficient assimilation by microbial biomass.
In a nutrient management strategy, this logic is invaluable: once the bacterial biomass is stimulated and fed, it more easily captures NO3 and PO4 in a coherent balance, and this biomass is then exported to the skimmer. This is why BEA Aequilibrium Z makes even more sense in tanks already geared towards bacterial growth or with well-managed carbon levels.
The dosage is intentionally simple: 1 capsule for 500 to 1,000 liters of actual water, or ½ capsule for 100 to 500 liters . For accurate dosing, the most practical method is to dilute the contents in 100 ml of aquarium water , then adjust the quantity according to the volume. The remaining product can be stored in the refrigerator for the next application, provided care is taken.
The important point: BEA Aequilibrium Z contains enzymatic components. To prevent particles from being deposited directly onto the coral tissue, it's best to add it to the sump rather than the main tank. To boost its effectiveness, the solution can be left to stand for 6 to 12 hours at approximately 24°C , away from direct sunlight, before being added.
The basic protocol follows an easy-to-maintain rhythm: 4 weeks of treatment , then 1 week without treatment . After this break, the aquarist assesses the state of the system (tests, substrate appearance, stability) and decides whether to repeat or switch to a different regimen.
Maturation: useful during start-up or transfer. Use the same dosage ratio (1 capsule/500–1000 L or ½ capsule/100–500 L) according to the schedule for 4 weeks, then a one-week break. For longer maturation periods, the cycle can be repeated.
Resolution: Recommended when there are medium/high nutrient levels, the presence of slime layers, algal/bacterial films, sludge, or low redox potential. After the one-week break, if symptoms persist, a new cycle is appropriate.
Maintenance: intended for stable and clean tanks, with little deposit and a generally high redox potential. Same setup: 4 weeks, then a one-week break.
BEA Aequilibrium Z combines particularly well with BEA Aequilibrium E and BEA Aequilibrium PRO : Z breaks down and makes nutrients available, while E and PRO help to assimilate and export them more efficiently. For a comprehensive approach, combining it with Aequilibrium A also helps support the overall balance of the system. The idea is simple: each product covers a specific aspect, and together they make biological management more consistent, more stable, and less prone to unpleasant surprises.
The capsules are sensitive to humidity: they must be kept closed, in a cool, dry place , and handled promptly after opening. This product is intended for technical use in ornamental aquariums and should be kept out of reach of children. It does not contain pathogenic organisms and is not intended for animal consumption or human use.
