Keeping the aquarium at its optimum levels is essential to guarantee the life of your fish, so one of the essential products is the filter, the choice of which will depend on the size and type of aquarium you have. It is also vital to have constant maintenance.


One of the parts that must be replaced are the cartridges, as this is where dirt accumulates. When changing the cartridge, make sure that the filter is in good condition and does not have any cracks or make any strange noises.


These Marina cartridges are suitable for the Marina i25 filter.
