The 40 litre Single Cylinder Sponge filter is a great filter for many home aquariums and can be attached against the side of the aquarium with the suckers provided. This is a really popular design of filter. It will come to you completely mature and ready to be installed into the tank.
It operates on air so an air supply from a suitable aerator is required in your tank for this filter to operate.
We rate this filter to efficiently break the waste down in a tank up to 40 litre volume that is sensibly stocked. As with all filters, if you feel your stocking density is high for the size of the tank, please consider purchasing a larger filter than you may think is necessary, especially if considering fancy goldfish, axolotl or other high waste producing species.
When your mature filter arrives, it will contain trillions of live nitrifying nitrosomonas and nitrobacter bacteria. It is important that your filter is installed into the tank very soon after delivery. It should not be allowed to dry out and fish should be introduced at the same time as the filter or within 48 hours of its installation.
Our pre-matured filters are matured in our bacterial digester. They have not seen fish and there is absolutely no chance of any disease cross contamination as there would be if you moved media from one fish filter to another. Please ensure your pH is above 6.5 and your kH is not below 4 to ensure that your filter bacteria can thrive.

Please note: This product has not been developed to deal with manual ammonia dosing or abnormal ammonia loading. It has been developed to break down the waste produced by aquatic life in Aquariums and ponds. If you are introducing high levels of ammonia into your tank then you are likely to experience spikes in water quality. An instant cycle of your tank is less likely to be achieved if additional ammonia is being introduced.
