for an AIO, i too like the AP24,
the BBQ skimmer i keep forgetting to scoop from you would fit perfect in there
if you did the ap24 w/ the sunpod.
or you could just choke up the $1700 for the elos 20g AIO(sortof)
but i almost prefer not doing AIO nano's...
that way you could spend your money on a really nice WM/SWC/deltec hob skimmer,
tunze nanostream pump, and say a nice tek/giesemann t5 light fixture,
then you'd have a really sweet little setup...you could hang the light fixture,
and have a nice topless custom nano made to your dim's,
skimmer w/ no pump in the tank, put the heater in the skimmer body,
and only 1 small tunze pump for flow on a black back would look saweeet!
