She had fish tanks like this, huge ones. It was impossible to create a vacuum at all, and when it did, the parts separated even through the lock. Fish stress, me stress. No thanks: (

It's no miracle. I consider the fact that the skimmer is made of two parts rather a disadvantage because of the poor quality of workmanship.
small
has a non-return valve to prevent water from returning to the aquarium
the intake has a part shaped for use in the corner of the aquarium
no water flow control (only higher models have it) - this is part A, see attached page from the manual
the gasket used at the joint is too small and leaks - air is drawn in
