agreed that it's not big enough to warrant two filters, I was just using it as an example really. I'm wondering though if you'd get enough flow by aiming a nozzle at the front corner - I wonder if the current hitting the corner would bounce it back toward the inlet basket sucking any poo and debris with it? ... the thing with flow and trying to create enough of it not to have dead spots is to play around with it.
When I had my Rio 180 I had just one JBL running and even though it was sufficient to filter (according to the manual) a tank of that size, I still got dead spots galore and the greasy film on the surface in the opposite side to the filter. In the end I added a small internal into the opposite corner and that did help. When the 240 arrived I knew I was going to have the same problem - if not slightly worse because it was a longer tank - and so that was why I decided on the two filters.
It's difficult to know how best to get what you want so throw the idea's around and somehow together we might come up with a solution lol
