Cade gravity top off

[Gone Reefin’]

Hello All. I have another thread going but not getting a lot of traction. I’ve identified a Cade as a candidate for my next tank. Does anyone have experience with this built in ATO in the back of the tank?

For the size I am looking at, the reservoir is like 12 gallons. How do you fill this? With a pump from ground level?

That reservoir on the back was why I passed on cade when i was looking for my new larger tank a while back. Front to back swim room is much more important and that reservoir takes up too much of that swim room IMO.

EDIT: you would have to fill it with a pump or buckets
