Hi all, my first post here after lurking for quite some time so hello.
I love the dual waterfall effect in this viv, how is it achieved? I can see the two lines coming in for the waterfalls, is there a pump in the bottom pond that circulates the water back up behind the background and splits the flow at the top?
Thanks, apologies for the newbie question but I've never done anything lke this before and I want to make sure it's done right when I do!
