It includes a bottle of sera filter biostart to accelerate biological filtration, ensuring crystal clear, biologically balanced aquatic environments with easy maintenance for all fish life stages. ## Description In order for cleaning bacteria to settle on or in a filter medium, the filter medium must have a certain surface structure. The larger the surface, the smaller the pores. From a surface area of about 450 m² per litre, the pores are so small that no bacteria can grow into it. As demonstrated in a university study, 270 m²/l is the optimal settlement area, as the pore size is precisely matched to the bacterial size and the bacteria can thus settle ideally. Sera Siporax offers exactly this surface. Cleaning bacteria in the filter ensure that harmful substances, such as B. excretion of fish, can be degraded in a biological way. In order to fulfill their task, they need a filter medium on and in which they can settle. However, the filter medium must meet some criteria so that it is ideal for colonization by cleaning bacteria. The size of the salt crystals corresponds to the size of the bacteria - this is particularly important as they determine the size of the pores as a placeholder. The mixture is pressed into a ring shape and at approx. Sintered to 780°C, i.e. fired. Then the rings are washed out so that the salt crystals are removed and the pore structure remains. ## Features - sufficiant for more than 200 liters of crystal clear, biologically clean aquarium water - for fresh and marine water - includes a bottle of sera filter biostart - Model number: 43253 ## Technical Specifications | Specification | Value | |---------------|-------| | Allergen Information | Allergen-Free | | Asin | B000A215HK | | Brand Name | sera | | Customer Reviews | 4.7 4.7 out of 5 stars (4,384) 4.7 out of 5 stars | | Global Trade Identification Number | 04001942084727 | | Included Components | One pack of sera siporax (15 mm) 1,000 ml | | Item Form | Granules | | Item Type Name | fish food | | Item Weight | 0.29 Kilograms | | Liquid Volume | 1000 Millilitres | | Manufacturer | Muc-Off | | Manufacturer Part Number | 8472 | | Model Number | 8472 | | Number Of Items | 1 | | Number Of Packs | 1 | | Pet Type | Fish | | Product Warranty | 2 year manufacturer | | Target Species | Fish | | Unit Count | 1000.0 millilitre | | Upc | 700580146760 | ## Product Details - **Brand:** sera - **Item form:** Granules - **Item weight:** 0.29 Kilograms - **Liquid volume:** 1000 Millilitres - **Number of Packs:** 1 ## Images ![sera Siporax Professional Fish Accessories, 15 mm, 1000 ml - Image 1](https://m.media-amazon.com/images/I/616tDOR3uDL.jpg) ![sera Siporax Professional Fish Accessories, 15 mm, 1000 ml - Image 2](https://m.media-amazon.com/images/I/61GTScy7nVL.jpg) ![sera Siporax Professional Fish Accessories, 15 mm, 1000 ml - Image 3](https://m.media-amazon.com/images/I/61-6HyPwVqL.jpg) ![sera Siporax Professional Fish Accessories, 15 mm, 1000 ml - Image 4](https://m.media-amazon.com/images/I/61JTKdYutWL.jpg) ![sera Siporax Professional Fish Accessories, 15 mm, 1000 ml - Image 5](https://m.media-amazon.com/images/I/61gavK66NVL.jpg) ## Available Options This product comes in different **Colour Name, Size Name** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Top product *by on Reviewed in the United Kingdom 29 October 2023* As usual top item from Sera! ### ⭐⭐⭐⭐⭐ Great media *by on Reviewed in the United Kingdom 3 June 2017* This is a great media for aquariums, it's very porous and will hold a lot of beneficial bacteriaI use this in marine so be aware the bottle of bacteria that comes in the box is for freshwaterI would recommend this ### ⭐⭐⭐⭐⭐ Very happy *by on Reviewed in the United Kingdom 11 June 2024* Great Service many thanks ## Frequently Bought Together - sera siporax Aquarium Bio-Filter Medium for 53 gal. | Maximal Optimization of Biological Filtration | 10.2 oz.
