A home aquarium is not just a beautiful decoration, a stylish interior element, or a relaxation zone for its owners. A transparent tank filled with water and aquatic pets represents a complex miniature world with its own unique ecosystem. The intricate ecological system inside an aquarium mimics natural conditions for all its inhabitants, including active fish, winding plants, mollusks, snails, and algae. However, an artificial reservoir can only function properly with the help of special equipment, treatments, and additional elements that maintain its viability. Ensuring the harmonious and stable operation of such a complex biocenosis requires proper care for both the tank itself and its inhabitants. Achieving biological balance is made possible by adding bacteria for aquariums. These beneficial microorganisms also enable natural cleaning without the use of harmful chemicals or aggressive detergents.
Bioproducts – the foundation of an effective biofilter

During aquarium maintenance, many users mistakenly interpret the term “biofilter.” It is often believed that specific aquarium filter media can provide sufficient filtration.
However, until bacteria colonize the surface of the filter, it only performs mechanical filtration by trapping fine particles. In reality, bacteria are the true biofilter. They can settle on any surface, whether it be the filter media, substrate, plants, decorations, or aquarium glass. By adding bacteria directly to the water, the system achieves the necessary balance and promotes natural purification. This is the simplest answer to the question of how to make aquarium water clear, eliminating unwanted buildup on walls, decorations, or the bottom.
Modern microbiological technologies and advancements offer aquarium owners extensive possibilities. Biotechnology-based aquarium cleaning products help combat dirt, algae, and deposits, ensuring the aquarium maintains an attractive appearance and crystal-clear water.
Unique bioproducts for solving difficult problems

EVOGEN CLARITY AQUA from Step2Clean is a comprehensive product that helps maintain a natural balance and creates a favorable environment. It is also the best option for cleaning an aquarium without draining the water. The product works by controlling the proliferation and development of the most common blue-green single-celled algae (cyanobacteria) and accelerating sludge degradation.
The solution for preventing water blooming in an aquarium is effective due to bacteria actively consuming carbon, potassium, phosphorus, and nitrogen. This process reduces the availability of these nutrients to algae, slowing down the growth and spread of cyanobacteria. At the same time, the product has no negative effect on the rightful inhabitants of the aquarium—fish, shrimp, mollusks, or higher aquatic plants.
Features of aquarium bioproducts and how to use them
When selecting what to add to an aquarium to prevent water cloudiness, it is essential to choose only high-quality products that address all existing issues and effectively manage biological waste. Algae treatment products from Step2Clean offer the following benefits:
- Improve the biocenosis of the aquatic environment to protect the health of its inhabitants
- Activate biological sludge degradation by working even in low-oxygen conditions at the bottom
- Eliminate unpleasant odors coming from the aquarium
- Achieve crystal-clear water without effort or harmful additives
The EVOGEN CLARITY AQUA treatment for preventing water blooming in aquariums comes in small 680 mg capsules. One capsule is sufficient for treating an aquarium of up to 200 liters, but the dosage can be adjusted to increase effectiveness. There is no need to worry if your aquarium is only 2 liters—the product remains completely safe even if the dosage is increased 1,000 times.
The product is extremely easy to use: simply open a capsule and pour its contents into the water. The frequency of application depends on the condition of the aquarium:
- For intensive treatment: apply daily for the first two weeks, then once every two days until the sixth week, and then weekly after the seventh week
- For preventive maintenance: apply one capsule per week
The bacteria in the product remain active in temperatures ranging from 5 to 50 degrees Celsius, making it suitable for any aquarium environment.
Key benefits of Evogen Clarity Aqua aquarium cleaner

Several factors contribute to the popularity of this bacteria-based treatment:
- Ease of use. Eliminates the need for frequent water changes and manual cleaning of decorations, reducing stress on fish by minimizing unnecessary movement.
- Continuous process. The bacteria work constantly, maintaining water clarity and a healthy environment for aquatic life, regardless of cleaning frequency.
- Effectiveness. Traditional mechanical cleaning and chemical treatments do not always achieve the same results as the steady, methodical action of bacteria.
- Cumulative effect. Regular use of the product significantly reduces future organic contamination.
- No resistance development. The bacteria-based treatment ensures long-term effectiveness without the risk of diminished results over time.
- Biological balance and safety. The absence of toxic elements guarantees complete safety for aquarium inhabitants.
- Reduced stress for fish. Frequent environmental changes negatively impact fish health, but bacterial filtration prevents shock disturbances in their habitat.
