A large tank, or two smaller tanks (1450 lbs limit)

[Muffin87]

The floor in my small apartment can take at most 41 pounds per square foot (200 kilos per square meter).
I can build a base to spread the weight of the aquarium(s) over a larger area, and achieve a 1450 lbs total weight limit.

I really can't decide between:

• WaterBox FRAG 105.4 AND MARINE X 60.2 connected to the same sump.
• Waterbox FRAG 145.5 with no future expansion possible.

I've gathered a bit of Pros and Cons.
Can someone with a good amount of experience help me decide which solution would be the best in the long term?
I know many end up wanting a second tank, for example.

I'm not very experienced, but I'm avid reader and researcher (of reef gear and science, rather than controversial and divisive livestock requirements).

	PROS​	CONS​
WaterBox FRAG 105.4 + MARINE X 60.2​	could use the MARINE X 60.2 as a display refugium; as a smaller tank to more easily broadcast feed sun corals; for a clownfish harem w/ BTAs; potentially for seahorses; for non-reef-safe fish (Dwarf angels?); FRAG 105.4 is a 4ft tank - could house at most a yellow or purple tang, if any tang at all.	cabinet space of the FRAG 105 is much more cramped in comparison to FRAG 145.5. harder to house a pair of mandarins (Tank bred)
Waterbox FRAG 145.5​	could house a pair of mandarins (tank bred) more easily. FRAG 145.5 is a 5 ft tank - could house a sailfin tang potentially?	If I go for a refugium, it's gonna be a small one. No dedicated space to broadcast feed sun corals.

I’m thinking about combining my two tanks in a corner of the room; one stand,sump, system, et. Corners are beefier anyway… I was thinking custom 90 degree stand …
anyway plan looks decent
