Thanks again, jumping in at the deep end I think.. pun intended!
I've seen some setups in relatively 'low' tanks...I really like the thought of a flow from one end to the other, ideally with a waterfall of sorts one end, a pump drawing water from the other end. Currently seeking out the correct pieces of wood that'll give the look i'm going for.
Going to delve into the galleries on here, its getting the picture in my head on to paper that's stumping me (again, pun intended)
