Filter bacteria are like the back-room heroes of your aquarium. You can't see them; you perhaps didn't even know they were there. But without filter bacteria, waste produced by fish, plants and decaying food doesn't break down effectively. This results in many of the fish health problems common to new aquariums. Filter bacteria can take several weeks to become established, but there is a sneaky shortcut. Add Fast Filter Start to your aquarium to add cultures of selected bacteria to your filter. This will rapidly start the waste breakdown process in your aquarium. Perfect for kick-starting your filter in an aquarium or re-establishing bacteria levels after completing routine filter maintenance. - Establish a balanced and healthy aquarium - Prevent fish loss - Can be used in any freshwater aquarium; with any Interpet treatment; and does not affect filtration ## Features - FAST ACTING - Fast Filter Start instantly adds vital beneficial bacteria to your aquarium for better filtration and lower fish mortality - GOOD BACTERIA - Add Fast Filter Start to your aquarium to add cultures of selected bacteria to your filter - KEEPS FISH SAFE - This will rapidy start the waste breakdown process in your aquarium, making the water safe for fish and other aquarium inhabitants - HELPS KICK-START A NEW AQUARIUM - Perfect for kick-starting your filter in a new aquarium or re-establishing bacteria levels after completing routine filter maintenance - BOOSTS BIOFILTRATION - This 125 ml bottle will treat 4,500 litres of water ## Technical Specifications | Specification | Value | |---------------|-------| | Allergen Information | Allergen-Free | | Asin | B01DVKMIYQ | | Best Sellers Rank | 6,079 in Pet Supplies (See Top 100 in Pet Supplies) 75 in Aquarium Water Treatments | | Brand Name | Interpet | | Country Of Origin | United Kingdom | | Customer Reviews | 4.6 4.6 out of 5 stars (1,670) 4.6 out of 5 stars | | Global Trade Identification Number | 00755349551033 | | Included Components | See Description | | Item Form | Liquid | | Item Type Name | Interpet Fast Filter Start Treatment, to Boost Aquarium Bio Filtration, 125 ml | | Item Weight | 0.22 Pounds | | Liquid Volume | 125 Millilitres | | Manufacturer | Interpet | | Manufacturer Part Number | 55103 | | Model Number | 55103 | | Number Of Items | 1 | | Number Of Packs | 1 | | Pet Type | Fish | | Product Warranty | Manufacturer Fault | | Target Species | Fish | | Unit Count | 125.0 millilitre | | Upc | 755349551033 | ## Product Details - **Brand:** Interpet - **Item form:** Liquid - **Item weight:** 0.22 Pounds - **Liquid volume:** 125 Millilitres - **Manufacturer:** Interpet ## Images ![Interpet Fast Filter Start Treatment to Boost Aquarium Bio Filtration, 125 ml, Fast Acting Beneficial Bacteria, Safe for Fish, 100 g - Image 1](https://m.media-amazon.com/images/I/71XufddOR-L.jpg) ![Interpet Fast Filter Start Treatment to Boost Aquarium Bio Filtration, 125 ml, Fast Acting Beneficial Bacteria, Safe for Fish, 100 g - Image 2](https://m.media-amazon.com/images/I/51PC7y98JyL.jpg) ![Interpet Fast Filter Start Treatment to Boost Aquarium Bio Filtration, 125 ml, Fast Acting Beneficial Bacteria, Safe for Fish, 100 g - Image 3](https://m.media-amazon.com/images/I/51l9p1L9gxL.jpg) ## Available Options This product comes in different **Colour Name, Size Name** options. ## Questions & Answers **Q: Is this a bio boost?** A: Hello . It's a waste of money, as it doesn't work ! I recommend the juwel bio boost tablet, if you want something to start off a new aquariums filter . I've tried both . You still need a minimum of 30 days for it to work though . I default to a fish less cycle now . I use a bio boost tablet plus ammonia solution . Hope that helps . **Q: My aquarium is small at only 10L. How much do i use and how do i measure such a small amount? Its less than 1ml !!** A: I have 24l and it works out as 0.75ml I use a 1ml pipette which has lines every 0.25ml (eg 0.5ml will be ideal for you its a bit more then the "dose" but it's closer then using over double what you need) **Q: Do you need to add ammonia as well as this product for a fishless first time cycle?** A: No just food or water from another tank will do Just keep an eye on the ammonia level it will eventually settle down **Q: Will this help a small spike in ammonia ive dobe complete water change and have slight ammonia level** A: This product will help the growth of good bacteria in your filter which will control ammonia but this will take some time. If your having spikes in ammonia regular water changes of between 10 and 20 percent will help reduce ammonia. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Ideal.
