55 Gal tall for 50-45 gallon tall

[brando]

Looking to build a refugium/sump for my 75 gallon. This glass tank doesn't fit. I need one less than 4 feet long and 14 inches wide. This is just a little too big. Trades only. Thanks.

I have 2 20 gal longs and a 29 gal. Would either of those work?
Also I have an eshopps sump available too.
