The JUWEL heater safely and reliably ensures the correct temperature in your aquarium. Depending on room temperature and aquarium size, your JUWEL heater will achieve a water temperature of around +28°C. Because it uses top-quality contacts and shock-proof, heat-resistant borosilicate glass (safety glass), JUWEL adjustable heaters meet the highest standards in both function and safety and, as you would expect, are TÜV/GS certified. In all Rio, Vision, Trigon, Lido and Primo aquariums, the heaters are placed out of sight in the filter casing and are perfectly integrated in the water circulation of the Bioflow filter system. This ensures an even, efficient distribution of heat through your aquarium.

Pond AQUA ESSENTIAL water conditioner is a highly concentrated all-in-one water conditioner that instantly makes tap water safe for fish by removing chlorine, chloramine and detoxifies heavy metals commonly found in tap water. Pond AQUA ESSENTIAL water conditioner instantly removes toxic ammonia, nitrate, and nitrite levels in your pond. Toxic ammonia is continually released by fish through their gills, urine, and solid waste. Uneaten food and decaying organic matter also add ammonia. Small amounts of ammonia stress fish; large amounts of ammonia will kill fish. This unique formula binds with ammonia, nitrite, and nitrate rendering them non-toxic and allowing the biofilter to remove them more efficiently. Use at pond start-up and whenever adding or changing water or when tested levels of ammonia, nitrates or nitrite are high.  Shake the bottle well directly before use. Add 50 ml per 500 gallons of pond water to treat tap water. Add 50 ml per 100 gallons of pond water to remove ammonia, nitrite, and nitrate. If after 7 days test results still show ammonia or nitrite, perform a partial water change. Best Before Guarantee: 30/01/2027

API AQUARIUM SALT is made from evaporated sea salt and is a must-have for your aquarium! AQUARIUM SALT promotes fish health by improving gill function, making it easier for fish to breathe. It also provides essential electrolytes that fish need to reach peak coloration and vitality. These electrolytes may be lost each time you perform a partial water change, and will need to be replenished. Use API AQUARIUM SALT in freshwater aquarium tanks when starting a new aquarium, and any time you perform a water change. Care should be taken when using salt in aquariums with live plants, as some plants may be sensitive. Add 1 rounded tablespoon for every 5 gallons or 0.5 teaspoon for every gallon of aquarium water.

Small floor cleaner for hard-to-reach areas removes sludge deposits in gravel thoroughly and reliably ideal for cleaning small aquariums and hard-to-reach areas suitable for all types of gravel can also be used in sand thanks to the freely adjustable bypass opening  including 2 m long, transparent hose for immediate start Large amounts of sludge in the aquarium are not only unsightly, but can also affect the quality of the water. The coarser the gravel, the more sludge collects in the gaps. Food disappears into the bottom before it can be eaten, and animal excrement and dead plant remains also collect and may not reach the filter. The Gravel Cleaner Nano can be used to gently clean small and hard-to-reach areas so that sufficient beneficial bacteria remain in and on the substrate. Particularly fine gravel and sand can also be easily loosened and cleaned thanks to the bypass opening. Compaction of the substrate can thus be reliably prevented. care and cleaning products for the aquarium The sera cleaning range includes a variety of products that make work in and around the aquarium easier.

Growth and immune food for Koi for year-round feeding floating pellets consisting of ring and core with probiotic active bacteria that stabilize the intestinal flora supports health and improves feed utilization Koi grow strong, develop a stable immune system and the water is less polluted with high protein content for healthy growth Probiotics are no longer only found in yogurts or as food supplements for humans - they have also taken their rightful place in ornamental fish nutrition. Since 2016, the intestinal flora stabilizer Bacillus velezensis (formerly B. subtilis ) has been approved for use in ornamental fish feed and is even expressly recommended by the EFSA (European Food Safety Authority) to improve growth and feed utilization. sera was the first manufacturer to react promptly in 2016 and launched an innovative probiotic koi food: “Koi All Seasons Probiotic”. As part of the rebranding of the sera brand, the name was changed to “Koi Professional Probiotic”. Koi Professional Probiotic is suitable for year-round feeding of koi at water temperatures above 8 °C. The co-extruded granules contain - in addition to the natural, functional ingredients that are already standard at sera, such as MOS, beta-glucans, Haematococcus algae, spirulina, etc. - the probiotic Bacillus velezensis , which stabilizes the intestinal flora of the fish. This promotes their health and improves feed utilization. The koi grow quickly and evenly and the water is less contaminated with fish-toxic and algae-promoting waste products. In order to benefit from these positive effects all year round, the special food should replace the respective seasonal food at least a few times a week throughout the year (at water temperatures above 8 °C). Of course, it is also excellently suited as a main food. Koi Professional line With the Koi Professional line, sera offers premium food types for Koi that take into account the needs of the cold-blooded animals during the different seasons (spring & fall, summer, winter). In addition, there are two functional food types, Koi Professional Color and Probiotic, that can be fed all year round.
