Pond water is clearer and the fish seem to recover quicker from their occasional ailments e.g. lesions from insect larvae, so they seem healthy. Buying another 5kg tub now for the Summer, I've also fed small amounts of this food during milder winter months when the fish have come up to the surface asking for food, it's rated from 5 degrees and koi are usually active around 5 degrees, so no need to buy a Winter food this one is fine. Review: Quality food to keep your kois healthy and pond water clean - I used this food for my kois two months ago. I am quite convinced now this is the best food I have ever used for my kois. I could see the water became cleaner and the kois were happier after 1 month. I checked the pond filter after two months and surprised to see how clean they were, almost no visible food waste on the sponges. Although the food is a bit pricey, it will save me a lot of maintenance time, effort and cost for the pond. The biggest koi in my pond is over 20 years old and requires clean water to keep it healthy. This is the exact food I need for her. The small kois in my pond are all this year’s new comers and they appeared to have grown considerably bigger in the two months. I am very pleased to have tried this food. ## Features - 【COMPLETE FEED FOR ALL POND FISH】: Medikoi Probiotic has been specially formulated over years of research and development to bring you a complete, professional diet for champion koi. The ingredients contained in Medikoi Probiotic are of the highest quality, and have been selected to support healthy growth, significantly enhance colour definition and optimise body shape. - 【HIGHLY PALATABLE & DIGESTIBLE KOI FOOD】: The high-quality ingredients in Medikoi Probiotic create a highly palatable and digestible food for your koi. It provides not only beneficial gut bacteria to help your fish break down foods more effectively, but also contains a prebiotic (fructo-oligosaccharide), a food for these vital bacteria to sustain them whilst they help maintain the wellbeing of your fish. - 【MULTI-SEASON KOI FOOD】: The nutritional balance of Medikoi Probiotic enables this complete feed to be fed over a large temperature range (from 5°C - 26°C), making this the best choice for your koi all year round. The pellets of Medikoi Probiotic have been vacuum-coated to prevent the proteins and oils in the food from leaching into the water and causing an unsightly surface slick to form. The abundance of vitamins and additives in Medikoi Probiotic will help keep your fish healthy whatever the weather, and the inclusion of probiotic bacteria ensures maximum uptake of nutrients by your fish, even in lower temperatures. - 【RAPID COLOUR ENHANCEMENT】: The inclusion of spirulina and astaxanthin provides a concentrated boost to the natural pigmentation of your champion koi. Reds will become more enhanced, and other colours will become brighter and perfectly defined against the purest white of your koi. - 【EASY NUTRITION STRATEGY】: For beautiful, healthy fish feed twice daily, a quantity that fish will likely consume within 10 minutes. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0058HVKE0 | | Age Range Description | All Life Stages | | Age range (description) | All Life Stages | | Allergen Information | Fish | | Animal Food Diet Type | Plant-Based | | Benefits | Promotes healthy growth and enhances colouration in pond fish | | Best Sellers Rank | 4,059 in Pet Supplies ( See Top 100 in Pet Supplies ) 68 in Aquarium Fish Food | | Brand | NT Labs | | Brand Name | NT Labs | | Breed Recommendation | All Breed Sizes | | Container Type | Bag | | Country Of Origin | United Kingdom | | Customer Reviews | 4.8 out of 5 stars 379 Reviews | | Dog Breed Size | Medium | | Flavour | Standard | | Item Form | Pellet | | Item Weight | 5000 Grams | | Item form | Pellet | | Manufacturer | NT Labs | | Manufacturer Part Number | S-3123 | | Number of Items | 1 | | Occasion | Birthday | | Package Size Name | 5 kg | | Pet Type | Fish | | Recommended Uses For Product | Daily Feeding; Pond Fish Nutrition; Multi Season Diet; Year Round Feeding; Colour Definition Enhancement; Low Waste Feeding | | Special Features | Probiotic and Prebiotic for Gut Health, Enhances Fish Coloration | | Special Ingredients | Spirulina | | Special ingredients | Spirulina | | Specific Uses For Product | Immune Support | | Specific uses for product | Immune Support | | Target Species | Fish | | UPC | 733809004367 | | Unit Count | 5000.0 gram | ## Product Details - **Age range (description):** All Life Stages - **Brand:** NT Labs - **Flavour:** Standard - **Item form:** Pellet - **Specific uses for product:** Immune Support ## Images ![NT Labs Medikoi Probiotic Multi-Season Pond Fish Food 6mm Pellets (5kg) | All year round koi food utilises probiotic bacteria for easy digestion to maximise nutrient uptake and body mass gain. - Image 1](https://m.media-amazon.com/images/I/71wd2LnzKhL.jpg) ![NT Labs Medikoi Probiotic Multi-Season Pond Fish Food 6mm Pellets (5kg) | All year round koi food utilises probiotic bacteria for easy digestion to maximise nutrient uptake and body mass gain. - Image 2](https://m.media-amazon.com/images/I/81v8AmV5MLL.jpg) ![NT Labs Medikoi Probiotic Multi-Season Pond Fish Food 6mm Pellets (5kg) | All year round koi food utilises probiotic bacteria for easy digestion to maximise nutrient uptake and body mass gain. - Image 3](https://m.media-amazon.com/images/I/71E-8GzLOrL.jpg) ![NT Labs Medikoi Probiotic Multi-Season Pond Fish Food 6mm Pellets (5kg) | All year round koi food utilises probiotic bacteria for easy digestion to maximise nutrient uptake and body mass gain. - Image 4](https://m.media-amazon.com/images/I/81q45Szs73L.jpg) ![NT Labs Medikoi Probiotic Multi-Season Pond Fish Food 6mm Pellets (5kg) | All year round koi food utilises probiotic bacteria for easy digestion to maximise nutrient uptake and body mass gain. - Image 5](https://m.media-amazon.com/images/I/81Efs5nUBcL.jpg) ## Available Options This product comes in different **Size** options. ## Questions & Answers **Q: I require 5kg bucket, can this be supplied ?** A: Yes if you look at our items we have for sale you will see that we currently have this on sale **Q: what is the shelf life of 5kl if kept in bucket in shed** A: My understanding of fish protein pellets and the fish oils in these pellets is that once opened they can go rancid after about 3 months. This is not discernible to us but is to the fish. Therefore i don't order more than about 3 months worth at a time. You can however bag them up into small bags and freeze them and they would last a year or so i would imagine. **Q: is this better than tetra pond koi food, my koi wont anything but tetra koi ?** A: NT Labs Probiotic is one of the best koi foods on the market, but if your koi won’t eat it, stick with the Tetra one that they like. Tetra fish food is also very good quality. **Q: Is this any good for growth.?** A: Good for overall fish health which leads on to growth but not a growth promotor. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Keeps koi and orfe healthy, keeps water clear *by E***R on 29 April 2026* I have fed my koi only with this food for the past 2 years, they all thrive, the youngsters are growing strong and those who are 20+ years old are full of energy and vibrant colours.
