hob refugium came with all the panels cut to size, rubberbands, glue,a syringe to apply glue and instructions. i only wish they supplied a few more baffles. its gonna be a dedicated refugium so i might just leave it as is and might add more baffles after i try it out to see how it performs. measures 24"L x 4"W x 12"H . i had to fill it 3 times before i got all the leaks and my glue job looks like crap but i think it should work fine. here is a pic of the almost finished product. i woulda done a step by step but only joined this forum when it was in this stage.
