UPS battery backup question

[mike31154]

Found the gizmo photo. It's called an air lift. I saw a post on a forum some years ago where a chap used a bunch of these to create a circular flow in a small tank.



I chose not to use these on my B11 backups since they are bulky & my sump less display already has enough gear distracting the view of what's important in there, so just use the small rigid tube. You could buy a hockey sock full of the battery air pumps for the price of a UPS & probably be fine with them during an outage until you got home.
