Operation Pressure pond filters with integrated UV unit are the combination of biological and mechanical filtration and contribute to the effectiveness by a UV-C pond clarifier. Due to their UV radiation, UVC pond clarifiers alterate the algae proteins´ tertiary and quaternary structure which causes their destruction. The algaes clump, thus forming large parts of particles that can be easily removed from the water circulation by the mechanical pond filtration of the pond filter. During the bio-mechanical cleaning microorganisms accumulate inside the filter and remove germs and bacteria from the water. By the way of mechanical filtration, floating particles and dirt remain in the pond filter and do not return into the pond water. It takes about 4–6 weeks for the filter bacteria to settle sufficiently inside the pond filter. Only then it is reasonable to make use of a UVC-pond clarifier. The so-called initial "starter bacteria" help to reduce the time for a new pond filter to start its operation. For this purpose this kind of bacteria (microorganisms) is grown in laboratories. Bacteria start being active at a temperature of approx. 10–12°C. The pond filter´s temperature should not exceed 40 °C. It is therefore advisable to place the pond filter in the shadow. It should not be exposed to direct sunlight. The pressure pond filter disposes of an integrated contamination indicator as well as a mechanical cleaning equipment for filter sponges, thus ensuring a quick and easy cleaning.

Rain Chains: The Perfect Blend of Function and Beauty for Your Garden Water Features When it comes to managing rainwater runoff while adding aesthetic appeal to your outdoor space, few solutions are as elegant and effective as rain chains. These beautiful alternatives to traditional downspouts have been transforming gardens and patios for centuries, originating in Japan where they're called “kusari-doi.“ Today, they're gaining popularity worldwide as both practical drainage solutions and stunning water features. What Are Rain Chains? Rain chains are decorative alternatives to conventional downspouts that guide rainwater from your roof's gutter system to the ground in a visually appealing cascade. Made from various materials including copper, aluminum, stainless steel, or iron, these chains create a mesmerizing water display during rainfall while effectively directing water flow. The chains consist of interconnected cups, links, or decorative elements that allow water to flow gracefully from one level to the next, creating both visual and auditory appeal. The gentle sound of water moving through the chain adds a soothing, meditative quality to your outdoor environment. Rain Chains as Effective Water Fountains Natural Water Movement Rain chains excel as water features because they work with gravity to create continuous water movement. During rain events, water flows naturally through the chain system, creating an instant fountain effect without requiring pumps or electricity. This makes them incredibly eco-friendly and cost-effective water features. Dual-Purpose Design Unlike traditional fountains that serve purely decorative purposes, rain chains provide essential drainage while creating beautiful water displays. This dual functionality makes them perfect for homeowners who want attractive water features without dedicating separate space or resources to ornamental fountains. Year-Round Appeal Even during dry periods, rain chains maintain their aesthetic value as sculptural garden elements. Their vertical design adds height and visual interest to landscapes, while their metallic finishes develop beautiful patinas over time, particularly copper chains that develop stunning verdigris coloring. Installation and Positioning for Maximum Effect Strategic Placement For optimal fountain-like effects, position rain chains where they can be easily viewed from indoor and outdoor living spaces. Consider sight lines from windows, patios, and garden seating areas. The vertical nature of rain chains makes them excellent focal points in garden design. Foundation Considerations Install a catch basin or decorative collection system at the base of your rain chain. This could be a traditional basin, a rain garden, or even a small decorative pond. The collection system not only manages water runoff but also creates additional visual interest and can support the fountain aesthetic. Height and Flow Dynamics The longer your rain chain, the more dramatic the water cascade effect. Chains spanning from roof gutters to ground level create impressive water columns during storms. Consider the water pressure from your roof system – higher flow rates create more dynamic fountain effects. Design Variations for Different Aesthetics Cup-Style Chains Cup-style rain chains, like those shown in the image, offer the most fountain-like appearance. Water collects in each cup before overflowing to the next level, creating deliberate cascade points that maximize visual impact. These work particularly well for creating dramatic water displays during moderate to heavy rainfall. Link-Style Chains Simple link chains provide a more minimalist aesthetic while still guiding water effectively. Water clings to and flows along the links, creating different visual patterns depending on rainfall intensity. Decorative Element Chains Some rain chains incorporate flowers, leaves, or geometric shapes as connecting elements. These designs can complement specific garden themes while providing unique water flow patterns. Maintenance and Longevity Rain chains require minimal maintenance compared to traditional fountain systems. Regular inspection for debris accumulation and occasional cleaning to maintain optimal water flow are typically sufficient. Metal chains should be checked for secure connections, particularly before storm seasons. Different materials offer varying maintenance requirements. Copper develops natural patina and requires no protective treatments, while painted finishes may need periodic touch-ups. Stainless steel options provide excellent durability with minimal maintenance needs. Environmental Benefits Rain chains contribute to sustainable water management practices. They slow water runoff, reducing erosion and allowing for better ground absorption. When combined with rain gardens or collection systems, they become part of comprehensive stormwater management solutions. The fountain-like water displays also create microclimat
