Market language

The terms a useful comparison should define

All-in-one
Filtration chambers sit behind the display, avoiding an under-cabinet sump while limiting equipment space
Reef-ready
The display, overflow, plumbing and sump are supplied, but most operating equipment may still be separate
Peninsula
A three-sided display with the overflow and service area concentrated at one short end
System volume
The display and filtration water together, which is different from usable display volume
