I just found the ehiem one for $50 and it has a fan to stop the food from clogging
I never need to go upstairs,but my brother,mum and dad see the tank every day and let me know when either a fish is missing,dead or looking sick,i really only go up there once a week or so,The main reason I want one of these is also because the bad lid,glass and light arrangement, I have to unplug the Light,remove it and then put it back,eachtime i feed. It really is annoying.
