It works perfectly. The surface of my tank has never been so clean

very good oil surface skimmer
. use with submersible pump (http://www.fish-street.com/sp_submersible_pump?category_id=63) and it's perfect

Très efficace pour retirer la pellicule grasse en surface, a coupler avec une pompe de type submersible (http://www.fish-street.com/sp_submersible_pump?category_id=63) pour etre parfait

no more oil on water surface for me.

a bit of a bitch to calibrate, but after that works perfectly

Is excellent.
