My impression of the purchase is good, buy it.

It is advisable to change the sponges inside the filter after a year. Wear out, become not as porous as new. Bacteria work here too. The lower sponge is only 50% active compared to the upper one.

Pros

Mine once every two weeks. External filter, eheim 350 classic, turn off for 5-10 minutes. While I wash sponges and I wipe the case. Basically the top sponge works. The thing is good! At least twice reduces the cleaning time of the sponge or synthetic winterizer inside the external filter!

Cons

1. When buying, I noticed that the neck, where to insert the intake pipe from the external filter line, is larger in diameter. True, the deeper it goes inside, the narrower it becomes. But still, the pre-filter does not hold, the tube does not fit tightly. It is necessary to compact either with a piece of foam rubber or synthetic winterizer. Those. its attachment to the external filter line is not fully thought out. 2. The suspension still does not completely penetrate the filter. When it is removed, part of it scatters around the aquarium.
