Jasyn, you're only going to need about 1 sqare inch of moss per square foot of wall. lay it thread by thread on your frame and let it grow in. It'll look cruddy for a month, and then seemingly overnight, you'll have a great looking moss wall. The thing is, if you put moss more than one layer deep, the bottom layers don't get any light and turn brown, possibly die and rot. if you start your moss out all the same layer, it'll grow in evenly. That's my 2 cents.

Be careful with the moss wall. I've heard of some instances of fish still getting trapped in there, which were mostly the ones that like to crawl into tight places.

Crazie's right on it. If you use two sheets of needlepoint mesh or nylon window screen wih the moss between, you 1) need to stitch the edges together with fishing line really tightly (like no fewer than a stich every third hole), 2) stitch all of the middle together less tightly (half as many stitches as the edges), and 3) make sure that it's 100% affixed to the back of the tank.

That third one is tricky. I'll be doing this with a 75 next summer, and the way I plan on doing it is to glue the really strong, tiny neodynium magnets every foot or so along the edges, and some in the middle, totally sheathing them in aquarium sealant, and putting them so that they face into the tank with the netting pinched between them and the back of the tank. (I'll use an equal number on the outside of the tank background to hold it in place.)
