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. Koi Professional Junior was specially developed to meet the nutritional needs of small Koi.

ParaGuard is the only fish and filter safe aldehyde based (10% by weight) parasite control product available (for parasites on fish). Unlike highly toxic and difficult to use formalin based medications, ParaGuard contains no formaldehyde or methanol and will not alter pH. KEY FEATURES: Eradicates ectoparasites and fungal, bacterial, and viral lesions Safer to dose than formaldehyde, formalin, and methanol Will not adversely effect bio-filter DIRECTIONS: Dosing Remove all invertebrates from the tank as well as any chemical filtration. Use 5mL (1 capful) of ParaGuard for every 40L (10 US gallons). Repeat this dose daily as required as long as fish show no stress. ParaGuard can also be used as a medicated dip. For 1 hour dips, use 3mL per 4 L (1 US gallon) in a container separate from your main tank. Dips may be extended if the fish show no evidence of stress. Keep in mind that many diseases linger in the water as well as on the fish. Giving a fish a dip treatment does no good if they go right back into infected water. Quarantine This is a tank set up in order monitor and medicate new fish before they go into the main tank. ParaGuard is gentle enough to use prophylactically (without visible symptoms) if needed. Quarantine times vary, but we generally recommend 2 weeks of treatment with ParaGuard to clear out any possible external infections. Sensitive Fish Some fish are more sensitive to medications than others. Eels, loaches, rays, sharks, and many others are well known for their sensitivity to all kinds of medications. If you suspect that your fish may be sensitive to medications, it is just fine to start with a partial dose and build up to the full dose over several days.Best Before Guarantee: 30/04/2027

Cupramine effectively eradicates oodinium, cryptocaryon, amyloodinium, ichthyophthirius, and other ectoparasites of both freshwater and marine fish. It is superior to copper sulfate, chloride and citrate: it is non-acidic, less toxic to fish, remains in solution, and does not contaminate the filter bed. It is superior to chelates: it is fully charged (ionic), active at low concentrations, and is removable with carbon. KEY FEATURES: Copper treatment for external parasites Active at low concentration (does not precipitate) Bound on amine so it is not as toxic to fish 100% Removable with carbon or Cuprisorb DIRECTIONS: Before Treating Remove all invertebrates - these are extremely sensitive to copper and will not tolerate treatment with a copper-based medication. Turn off UV filters, ozone filters, and remove chemical filtration like MatrixCarbon and Purigen. Do not use in conjunction with any other medication. Do not use any products which contain reducing agents (conditioners, ammonia binders, etc.) while using Cupramine. Treatment If the bottle has a dropper cap, use 20 drops (1mL) per 40L (10.5 US gallons) the first day, wait 48 hours, then repeat. On non-dropper caps, each inner ring is 1mL. In freshwater use half dose. Final copper concentration is 0.5 mg/L (0.25 mg/L in freshwater). Leave at this concentration for 14 days. Do not redose without testing. If tank has ever been treated with an ionic copper (e.g. copper chloride, sulfate or citrate), test copper level after initial dosing. Although most fish tolerate Cupramine to 0.8 mg/L, it is not advisable to exceed 0.6 mg/L copper. Finish the Full Treatment Ich, velvet, and many other parasites spend a large portion of their life cycle as a cyst that is immune to medication and hiding in the substrate of your tank. Remember that you need to finish the full treatment even if you can't see parasites on the fish! After Treating Cupramine can be removed using carbon. Leave the copper-absorbing media in your tank for at least a week after the copper concentration has reached 0 to ensure all traces of the medication have been completely removed.

Water conditioner against fungal infections (Mycosis)  Effectively combats infections by fungi (e.g. Saprolegnia) on fish and spawn in freshwater. The water conditioner can also be used in case of external injuries as well as against skin and gill flukes and Transversotrema. Invertebrates do not tolerate the treatment. Additional use of the care product sera ectopur supports effective treatment. Too low water temperatures support the growth of fungi.

Breathe freely with purifying Emergency support in case of acute oxygen deficiency Stress reduction by optimized oxygen supply Easy and safe application Supports the breakdown of sludge The breath of the aquarium inhabitants as well as other natural breakdown processes constantly consume oxygen. Certain circumstances may lead to acute deficiencies. This includes high water temperatures, strong organic pollution and oxygen consuming disease treatments. While even little undersupply already causes stress, extreme lack of oxygen often leads to the death of fish. sera O2 plus - simply sprinkled into the water - immediately adds oxygen and thus improves the living conditions for all aquarium inhabitants. Additionally, the breakdown processes run faster in case of good oxygen supply, thus the aquarium will remain crystal clear and without unpleasant odors.

Healthy cleanliness Removes drug residues after treatment Removes harmful substances and dyes Does not contain phosphate Long-term effective Immediate help in case of acute poisoning For clean safe water Following the use of medicinal products, it is necessary to remove their residues as quickly as possible so that the water is not unnecessarily burdened and a new stress factor is not created. Special activated carbon sera super carbon removes residues immediately, effectively, without side effects and pH neutral. By using coal pellets, these environmentally hazardous substances can be disposed of completely and without problems in household waste. sera super carbon is also suitable for use in case of acute poisoning (e.g. when it is suspected that poisonous substances have entered the aquarium during renovation work, from inappropriate furnishings, overdose, etc.) and also when removing water discoloration Dosage: 10g of Sera super carbon in the filter for every 20 liters of water. Rinse with water before use.

Water conditioner against Camallanus, Capillaria and other Nematodes Water conditioner for the reliable and gentle removal of parasitic roundworms (nematodes) in freshwater and marine fish. Nematodes such as Camallanus sp., Capillaria sp. and discus pinworms (Oxyuris sp.), can become a severe problem that often remains unnoticed for a long time especially in freshwater aquariums. Cichlids are particularly frequently infected. Invertebrates such as shrimps and crayfish do not tolerate the treatment.

Water conditioner against single celled skin parasites such as Ichthyophthirius multifiliis Water conditioner for freshwater aquariums for the safe, quick and reliable removal of Ichthyophthirius multifiliis (pathogen causing white spot disease) and many other single celled skin parasites (e.g. Ichthyobodo, Apiosoma, Trichodina, Chilodonella) as well as infections by fungi. The product is colorless in water and therefore particularly well suited for using it in display aquariums and sales setups. sera med Professional Protazol is very well tolerated by plants and invertebrates (e.g. snails and shrimps).
