UV lamps for garden ponds
UV lamps (UV sterilizers / UVclarifiers) are technical devices that reduce the amount of algae and pathogens in water using ultraviolet light. In ponds, they are one of the most effective ways to keep water clear and healthy without excessive chemical intervention.
17
Filamentous algae and green water in a garden pond
Algae are a common part of any aquatic ecosystem. When in optimal balance, they improve water quality and provide food for some microorganisms. However, if they grow beyond their natural limits, they can become a problem — most commonly in the form of filamentous algae and green water. These two forms of algae differ in their nature, requirements, and even methods of control.
17
Biofoam for garden pond
Biofoam, also known as biological foam or bio-sponge, is a synthetic porous material used in garden ponds and aquariums as a biological filter. It serves to develop beneficial bacteria that convert harmful substances in the water into less harmful ones, thereby promoting stable water quality and the health of fish and plants.
17
Drum filters for garden ponds
Drum filters are modern mechanical-biological filtration systems that can handle high fish and dirt loads. They are especially popular in Koi ponds and larger garden ponds where classic filters are not enough.
16
Skimmers for garden ponds
Skimmers are special devices designed to remove debris from the surface of a pond, such as leaves, twigs, insects or organic waste that would otherwise decompose and degrade water quality. They are a key part of maintaining a clean and healthy water body, especially in ponds with fish such as koi or sturgeon.
16
Aeration for a garden pond
Aeration is one of the most important elements of maintaining a healthy pond, as it increases oxygen levels in the water, promotes biological filtration, and improves overall water quality. Proper aeration is especially crucial during the warmer months, when oxygen levels naturally drop and fish are more susceptible to stress and disease.
16
Activated carbon and zeolite
Activated carbon and zeolite are often used in garden ponds as part of the filtration system. These are mineral and chemically active materials that significantly contribute to water clarity, odor reduction and the removal of harmful substances. Although they are not a biological filter like biofoam or Japanese mat, they supplement filtration and help maintain a healthy ecosystem.
16
Bead filters for garden ponds
Bead filters, also known as bead filters, are highly efficient biological-mechanical filters designed primarily for Koi ponds and large garden ponds. They use small plastic beads as a filter medium, which provide a huge surface area for nitrifying bacteria. Their principle is simple but effective - it allows for clean, transparent water and a stable biological balance.
16
Splash filters and biofilters for garden ponds
Filtration is a key element of a healthy pond. Without the right filter, the water will quickly become cloudy, algae will grow, and fish will suffer from stress or disease. Splash filters and biofilters are two main filtration systems that are often combined to achieve optimal water quality.
15
Starter, maintenance and sludge bacteria
Bacteria are a key element in the biological balance of any garden pond. Used correctly, they can improve water quality, prevent algae growth, support fish health and break down organic waste. There are starter, maintenance and sludge bacteria on the market, which have different functions.
15
Sturgeon feed
Sturgeons are unique ancient fish that stand out not only for their appearance but also for their specific eating habits. They are bottom omnivores/carnivores with a preference for animal food and their proper nutrition is crucial for growth, health, immunity and lifespan in the garden environment.
15
Japanese garden pond mat
Japanese mat is a special biological substrate used in garden ponds, especially in koi ponds and ornamental water tanks, to support biological filtration. It is characterized by a structure that supports the growth of nitrifying bacteria, helps stabilize water quality, and at the same time provides mechanical filtration.
15
Chamber filters for garden ponds
Chamber filters are one of the most effective filtration systems for medium and larger garden ponds. They use multiple chambers in which the water is gradually cleaned, and combine mechanical and biological filtration. Their design allows for high efficiency while maintaining the biological balance in the pond.
15
Substrates, fertilizers and flower pots for a garden pond
For a healthy and beautiful pond, substrates, fertilizers and pots are just as important as the plants themselves. The right combination will ensure optimal growth, flowering and ecological balance.
14
PVC foil for garden pond
PVC (polyvinyl chloride) sheeting is one of the most commonly used solutions for waterproofing garden ponds and fishponds. It is used as an internal "fabric" that keeps the water in the pond without leaking into the surroundings.
14
Japanese oysters for the garden pond
Japanese oyster shells are not living organisms, but a natural pond additive used primarily as a mineralizing substrate, decoration, and water chemistry stabilizer. Their use is popular with Koi pond and garden pond owners who want to support water quality without chemicals.
14
Hobby pressure filters for garden ponds
Hobby pressure filters are practical, closed filtration devices that enable effective mechanical and biological filtration in small and medium-sized garden ponds. They are suitable for hobby gardeners and owners of smaller Koi ponds who do not want to invest in professional systems.
14
Water lilies in the pond
Water lilies (genus Nymphaea) are among the most popular aquatic plants for garden ponds. They not only add aesthetics and color, but also have an important ecological function, supporting the balance of the entire ecosystem.
13
Winterizing a garden pond
Winterizing a garden pond is crucial for the survival of fish, plants and microorganisms during the winter and for a quick start of the biological balance in the spring. Proper winterization minimizes the risk of fish death, decomposition of organic material and damage to filtration and technical equipment.
13
Vacuuming a garden pond
Vacuuming your pond is one of the key maintenance activities to maintain healthy water and a clean environment for fish, plants and microorganisms. Proper and regular vacuuming helps prevent the buildup of sludge, organic waste, leaves and other debris that can degrade water quality and promote algae growth.
13
Feed for fry
"Fry" refers to young fish immediately after hatching or in the first weeks/days of life. During this period, their nutrition is fundamentally different from adult fish, as they grow rapidly, their metabolism is intense and they have specific needs:
13
Aquatic and marsh plants for the pond
Aquatic and marsh plants are the foundation of a healthy pond ecosystem. They not only enhance aesthetics, but also fulfill ecological functions that keep the water clean and stable.
12
Garden pond lighting
Garden pond lighting is not just an aesthetic addition. The right lighting can enhance the beauty of the pond, promote the health of plants and fish, and also ensure safety when moving around the pond at night.
12
Food for Koi Carp
Koi are some of the most demanding and beautiful ornamental fish you can have in your pond. Their health, growth, coloration, and lifespan depend largely on what you feed them. Koi food is not just food – it is a source of energy, nutrition, and often preventive medicine.
12
Ozone in a garden pond
Ozone (O₃) is a strong oxidizing gas used in aquaculture and ponds to disinfect water, eliminate organic contaminants, algae and pathogens. Ozone can significantly improve water quality, but it is also a highly reactive substance that can damage fish, plants and biological filtration if used incorrectly. Therefore, it is important to understand it in depth.
12
Biobeads, Helix, bacterial houses and bioblocks
Biological filtration is key to healthy pond water. Mechanical filters capture impurities, but only biological media converts toxic substances (ammonia, nitrites) into less harmful nitrates.
12
Slit filters for garden ponds
Slotted filters are specialized mechanical filters used primarily in Koi ponds and larger garden ponds where it is necessary to effectively remove solids and ensure clear water. Their name comes from the slots or holes through which water passes while larger particles are trapped.
11
Garden pond pumps
The pump is the heart of the circulatory system of every garden pond. Without the right pump, no filtration, waterfall, fountain or biological water balance can function. It is a device that maintains the water flow, ensures oxygenation, co-creates water effects and optimizes the work of filtration systems.
