- A current larger C-Series hang-on reference when a compatible thicker rear rim, the maintained waterline and its 70-US-gallon ceiling fit the aquarium plan; the ceiling has no documented lower endpoint.
Tradeoffs to weigh
- Its larger housing needs more rear and overhead service room; no lower tank-volume boundary, litre basket capacity or high-waste rating is documented here.
