Yes the skimmer its working but not in proper manner as i told u . BTW when i was there your tank already shut down can't see anything only see dirty water in the tank.And B4 i went down i keep asking u whether its in good working condition. U keep saying it working. Pls check your SMS lah. BTW $10 is nothing but u waste my trip , time and energy to get to your place to get a faulty item. Put yourself in my shoe how do feel. And i dont think others like it also. Ok lah forget it lah u win lah.
