well. this is somewhat embarrassing. so yes, i have a 16 gallon tank. thing is, i knew that before, but i spent so much time online looking through prices and all that i think i just got confused? oh well, either way, i was wrong and i apologize. anyhow. i got under there and sure enough, 3 straps. i snapped a few pictures here too, with the phone and on the ground, so not too great, but you get the idea. so what is going on here? and back to the original point, can i just throw the 23.5 in with no worries even though its physically longer?
