The tank will be 120x36x27 (500g)
I'm considering doing a coast-to-coast external overflow on the back panel. Does anyone have one on a tank this size, and, are you happy with it? The alternative is two smaller external overflows. Both options would be running bean animal.
Other things
I would have 4 return holes and 2 closed-loop holes drilled for the UV system. Is it overkill to have some holes drilled on the bottom panel for closed-loop flow?
