The 30 litre corner filter is a great little filter for the nano or betta aquarium. 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 30 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.
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.
As with all of our filters, if you would prefer to purchase a filter that is not pre-matured, please take a look in the new filter section.
Our pre-matured filters are matured in our bacterial Bioreactor. 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 esnure that your filter bacteria can thrive.
