I went from this 30g which is an old picture because the plants were covering everything and pushing on the glass top

to this 70g... Thank you craigslist!
I am going to use my old waterfall I built and create another false bottom for this tank. What I am trying to find are some simple ways to mount the plants so I can have a nice grass bottom for the pdf's. I don't want to go through the whole greatstuff stage at this time unless it is the only way to mount them on the background of the tank. I am trying to keep everything simple because I am transferring to another college to finish out my D.C. and this tank is going with me so any ideas, pictures, urls you have let me know! Also should I mount some 80mm fans to those vents for air circulation?
Oh, using a tape measure to determine the size of the tank before buying does not put in perspective of how large this thing is lol!
