So- I have to ask- how do you manage the water up there? Do you have a drain and fresh water source? I understand that you just do 100% water change as needed. But it looks like it would be difficult to not spill that water all over the floor and have it end up in someone’s bedroom below.
Good question I have around 20 water boxes and aquariums. I make an exchange every second week but only from those which really need a water change. Some boxes stand clean because of fishes and plants so I only have to change it 3-4 weeks.
The bathroom is one floor under the roof bottom. I have a long pipe which reach from the bathroom to the roof. With under-inflation I can pump the boxes empty easily. I hope you understand what I try to explain
I take the pipe from box to box and with this way I need an hour circa to clear every box.
