What size of tank do you have it on, I have a 180, but I'm really looking for 3 or 4 degree pulldown. I see it's rated for 5 degree for a 150, does that sound about right. Also, is it pretty quiet, the tank is in the living room, and it will need to sit beside it. If so, I'm pretty sure I want it, just let me know if you think it will work for the size of tank.
