Hey, I have a 3' tank running, and I would like to
get a nice sized sump/refugium for it - possible
without dismantling it, of course :-)

The cabinet opening is 24" long and 17" high...
Of course I could slide there a tank 24" long, but
maybe a longer one will get there angled in somehow ?

Anybody knows a place to get 24" long sump, or couple
of inches longer, with a compartment for refugium ?
Is this even possible or I should build a custom one ?
