Well, security came around yesterday and told me that it was against company policy to have aquariums with aerators/pumps. So the tank pump got unplugged. Apparently this is okay. We'll see if I catch any more flack.
I can understand not wanting external filters, or bubblers, that in the even of a failure could leak, but that is the beauty of a Spec, it is all internal and these problems don't occur. Maybe I should have questioned them a bit more, but i was caught off guard, and i did not feel like arguing with them.
So my tank is now going to be plant based filtration only. I will still plug the pump in to eject water for my water changes, but that is the only time the filter will run.
What considerations do I need to make now. Obviously i am not going to be adding any fish. I know I will also need to increase my water changes. Anything else you guys would suggest?
