Finally, a larger Ablaichkasten

The box is significantly larger than what you get otherwise available "by default". In turn, the meshes of the net are much larger ... estimated at mesh of 1-1.5 mm is not the power of very small fish.
The network sits very tightly, making the one hand, well, if you occasionally want it free of algae, on the other hand it has with me a few holes ... This can be but slightly mend.
The pelvis is attached by four suction cups directly to the aquarium glass. Unfortunately, this is for many smaller fish trap. You do it though, in the space to swim (about 3-5 mm), but do not come back out ... I have the upper suction pads replaced with larger, leave more space for the disc.
