what are the dimensions of this thing? i ask because i have a 2.5g nano that i want to set up the hagen system w/ the ladder and im not sure if the ladder will fit... i have about 5.5 inches from the gravel to the top.
The Hagen ladder is 7½" tall by almost 3⅛" wide. Look at the diagrams [h] and on page 8 of 12. There's 3 different settings on the ladder. The lowest is 1" from the bottom, the next is 2½" from the bottom and the highest is 4" from the bottom. http://www.hagen.com/pdf/aquatic/CO2_Manual.pdf
