The ceramic base is crafted with a unique blend of tourmaline, maifanitum, actinolite, and volcanic rock minerals. These minerals emit far infrared (FIR) waves with a wavelength between 4-12 μm, enhancing water clarity and eliminating unpleasant odors. A gentle 0.06mA circuit generated by tourmaline aids in breaking down chlorine found in tap water during water changes. The Bio-Spheres are exceptional for cultivating bacterial colonies in the form of Bio-Nano Composite Films, promoting the growth of various bacteria and fungi on their extensive surface area, including nitrifying bacteria (such as Nitrosomonas, Nitrosococcus, Nitrobacter, and Nitrococcus), yeast, and phototrophic prokaryotes. Specifically designed for freshwater aquariums only (not suitable for marine environments); Popular in freshwater aquariums across China and Southeast Asia for over ten years; Each variant offers unique advantages and features tailored for various types of freshwater aquariums; Nano-Tech Bio-Spheres are crafted from inert ceramic materials, enhanced with additional ingredients for distinct characteristics; All Nano-Tech Bio-Spheres undergo a firing process in an oven for over six hours, resulting in a highly durable and stable bio media that lasts for years. Offered in 1kg and 2kg packaging options

Effectively eliminates nitrate from your aquarium Our unique technology is crafted to encourage the growth of anaerobic bacteria. These anaerobic bacteria finalize the nitrification process by converting nitrate into nitrogen gas, helping to remove excess nutrients from the aquarium. 2 Blocks can treat up to 1,000L / 264 Gal. Facilitates the nitrogen cycle through denitrification, by fostering anaerobic heterotrophic bacteria (including types from the genera Paracoccus denitrificans and various pseudomonads), which transform nitrate into nitrogen gas. The Nano-Ceramic beads in the Anaerobic-Blocks are specially enhanced with our proprietary technology, allowing them to effectively cultivate anaerobic heterotrophic bacteria that thrive in low-oxygen environments.

sera omnipur A Water conditioner designed to combat common ornamental fish ailments in freshwater This versatile water conditioner acts quickly and effectively against nearly all pathogens found in freshwater environments. It addresses bacterial infections (such as Columnaris, Aeromonas, Pseudomonas, as well as mouth and fin rot), fungal infections (for instance, Saprolegnia), single-celled skin parasites (including Ichthyobodo (Costia), Ichthyophthirius, Chilodonella, and Trichodina), along with skin and gill flukes. This treatment is also effective for disinfecting external wounds and helps to prevent secondary infections.

Nourishing and immune-boosting food for Koi, designed for feeding throughout the year floating pellets featuring a unique ring and core structure enriched with probiotic active bacteria to enhance and stabilize intestinal flora promotes health and optimizes feed utilization Koi develop robust health, build a strong immune system, and contribute to cleaner water high in protein for optimal growth Probiotics are now recognized beyond yogurts or dietary supplements for humans—they have become an essential part of ornamental fish nutrition. Since 2016, the intestinal flora stabilizer Bacillus velezensis (previously known as B. subtilis) has been approved for inclusion in ornamental fish feed, receiving explicit endorsement from the EFSA (European Food Safety Authority) to enhance growth and feed efficiency. sera was the pioneer to respond swiftly in 2016 by introducing an innovative probiotic koi food: “Koi All Seasons Probiotic.” As part of the brand's rebranding initiative, the name was updated to “Koi Professional Probiotic.” Koi Professional Probiotic is ideal for year-round feeding of koi when water temperatures exceed 8 °C. The specially co-extruded granules include not only the natural, functional components that are typical of sera, such as MOS, beta-glucans, Haematococcus algae, spirulina, and more, but also the probiotic Bacillus velezensis, which supports the fish's intestinal flora. This enhances their overall health and boosts feed efficiency. As a result, koi grow rapidly and uniformly, while the water remains less polluted by harmful waste and algae-promoting substances. To reap these benefits throughout the year, this specialized food should replace seasonal diets several times a week, as long as water temperatures are above 8 °C. It also serves excellently as a primary food source. Koi Professional line Within the Koi Professional line, sera provides high-quality food options tailored to the unique needs of cold-blooded fish during various seasons (spring & fall, summer, winter). Additionally, there are two functional food options, Koi Professional Color and Probiotic, which are suitable for year-round feeding. Koi Professional Junior has been specifically formulated to cater to the dietary requirements of young Koi.

ParaGuard is the sole fish and filter safe aldehyde-based (10% by weight) solution for controlling parasites in fish. Unlike the highly toxic and challenging formalin-based treatments, ParaGuard is free from formaldehyde and methanol and will not disrupt pH levels. KEY FEATURES: Effectively eliminates ectoparasites along with fungal, bacterial, and viral infections Safer to administer compared to formaldehyde, formalin, and methanol Does not negatively impact bio-filter DIRECTIONS: Dosing Remove all invertebrates from the aquarium as well as any chemical filtration. Administer 5mL (1 capful) of ParaGuard for every 40L (10 US gallons). Repeat this dosage daily as needed, provided the fish do not exhibit signs of stress. ParaGuard can also be utilized as a medicated dip. For a 1-hour dip, use 3mL per 4 L (1 US gallon) in a container separate from your main tank. Dips can be prolonged if the fish exhibit no signs of stress. Remember, many diseases can persist in the water as well as on the fish. A dip treatment is ineffective if the fish are returned to infected water immediately after. Quarantine This involves setting up a tank to monitor and treat new fish before introducing them to the main aquarium. ParaGuard is gentle enough to use preventively (even without visible symptoms) if necessary. Quarantine durations can vary, but we typically suggest a treatment period of 2 weeks with ParaGuard to eliminate any potential external infections. Sensitive Fish Certain fish are more susceptible to medications than others. Eels, loaches, rays, sharks, and many others are recognized for their sensitivity to various treatments. If you think your fish might be sensitive to medications, it’s perfectly fine to begin with a reduced dose and gradually increase to the full dosage over several days.Expires on 03 Feb 2030
