So I've been given this tank for free 
The filter is only the second I've ever seen and I'm not quite sure how it works. Here are some pics
The box
The bit stands up inside the box with the motor on top
These are the sponges in the order I took them out
And this is to be changed every month-it is filter floss? Where does it go?
I was expecting some ceramic media?
I can't work out which are the water intakes. I'd like to know how low the water level could be?
And also, would it work lying on its side?
Thanks for any help
