The ceramic base is enhanced with a unique blend of minerals that emits negative ions. These negative ions play a key role in neutralizing water and keeping the pH level between 7.0 and 7.2. They promote the development of nitrifying bacteria colonies and enhance water clarity. The Bio-Spheres are particularly effective in fostering bacterial colonies through Bio-Nano Composite Films, which support a variety of bacteria and fungi on their extensive surface area. This includes nitrifying bacteria from genera such as Nitrosomonas, Nitrosococcus, Nitrobacter, and Nitrococcus, as well as yeast and phototrophic prokaryotes. Specifically designed for freshwater aquariums only (not suitable for marine environments); Widely utilized in freshwater aquariums throughout China and Southeast Asia for over a decade; Each variant offers unique advantages and properties tailored for various types of freshwater aquariums; Nano-Tech Bio-Spheres are crafted from inert ceramic material, with added components to enhance specific traits; All Nano-Tech Bio-Spheres undergo a firing process lasting over 6 hours, resulting in a highly durable and stable bio media that can last for years. Available in 1kg and 2kg packages.

Balance is a carefully formulated mix of sodium and potassium hydroxides featuring a NSW ratio (27:1) of sodium to potassium, designed to prevent ionic imbalance during prolonged usage. KEY FEATURES: Part of the premium AquaVitro collection Stabilizes the carbonate buffer system ratio Increases pH without altering calcium and alkalinity Contains a hydroxide blend DIRECTIONS: Balance should be utilized to increase pH when all other factors (alkalinity, calcium, magnesium) are within optimal ranges, but the pH level remains low. The quantity of Balance required to achieve the desired pH will vary significantly based on the buffering capacity and quality of your aquarium water. As a general guideline, 5mL can elevate 55L (15 US gallons) of saltwater by roughly 0.1 pH units. Introduce Balance in small amounts, and monitor the pH after a minimum of 3 minutes before adding further increments. *Product not available for online sales.Expires on 05 Jan 2027

Pond AQUA ESSENTIAL water conditioner is a powerful, concentrated all-in-one solution that instantly transforms tap water into a safe environment for your fish by eliminating chlorine, chloramine, and detoxifying heavy metals typically found in tap water. This conditioner effectively neutralizes harmful ammonia, nitrate, and nitrite levels in your pond. Fish continuously release toxic ammonia through their gills, urine, and solid waste, while uneaten food and decomposing organic matter contribute to ammonia levels as well. Even small quantities of ammonia can cause stress to fish, and high levels can be fatal. This innovative formula binds with ammonia, nitrite, and nitrate, making them non-toxic and enabling the biofilter to eliminate them more efficiently. Apply it when starting up your pond, whenever you add or change water, or when tests indicate elevated levels of ammonia, nitrates, or nitrite. Shake the bottle thoroughly just before use. For treating tap water, add 50 ml for every 500 gallons of pond water. To eliminate ammonia, nitrite, and nitrate, add 50 ml for every 100 gallons of pond water. If ammonia or nitrite levels remain after 7 days, conduct a partial water change. Expires on 30 Jan 2027

API AQUARIUM SALT is crafted from evaporated sea salt and is essential for your aquarium! AQUARIUM SALT enhances fish health by aiding gill function, which facilitates easier breathing for your fish. It also supplies vital electrolytes that are crucial for fish to achieve optimal coloration and overall vitality. These electrolytes can be diminished during partial water changes, so it's important to replenish them. Utilize API AQUARIUM SALT in freshwater tanks when setting up a new aquarium, as well as during any water change. Please exercise caution when using salt in tanks with live plants, as certain plants may be sensitive to it. For every 5 gallons of aquarium water, add 1 rounded tablespoon or 0.5 teaspoon for each gallon. Expires on 30 Apr 2028

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.
