the cans range from $4.00 to $7.00 for the fire resistant one.

the original is $4.00
large expand is $5.00
the min expand is $6.00
and the fire resistant one is $7.00

there are larger 24oz cans, but they seem to have a higher cost per OZ for some reason. they clam to have less splatter and wast thus the higher cost.

im thinking, for a 38 gal tank. using the min expand, one can each for top and bottom. and one can for every 6" of height or would it be more like one can for every 4" of height

its about 3 foot high so 8 cans total, at a cost of $48.00
or using the 4" rule its 11 cans total, for $66.00

using the max expanding, it would be more like 6 cans at a cost of $30

clearly covering it on the out side and turning it off when not in use, would be much easier.
id do this mod, but we all ready have a marathon tank and its foam from the factory.
