Green Thumb: I went to Rona and saw some glue for plastic which said it could be use in aquarium without problem. Gave it a try and it worked. Its called: Extreme Repair from Lepage
Edward: I have th module to make the Prolifux control it but have not installed it yet. For now, its running at maximum capacity and its so quiet, that its not even noticeable if you dont concentrate on it. Its also strong enough that at the end of the room, if i put a paper over the arch of the entrance, its going to swing a bit.
