Review on Aquael Fan Filter Mikro Plus by Ewa Marczewska ᠌

I have an aquarium of 54 liters, in fact the water in it is 50 liters. Before that, there was an internal filter EHEIM PICKUP 60 (300 l / h, for 30-60 l), crystallized water literally overnight after cleaning. But I did not like its size and not the ease of cleaning it. This one is almost the same in terms of characteristics, but it manages to make water clean in a day and small fractions are still visible, perhaps due to the high porosity of the sponge. The sponge itself is not clogged evenly, half is dirty, the back is clean, in its design, it seems to work half. It seems to me that such a filter is up to a maximum of 40 liters, but not like 60. I will probably change it to Fan 1 Plus.
