Well i now own a 90 gal tank

[Paul]

Space has now gotten tigher in my apt, but I was just too weak to resist. Got the tank and stand for $75. Couldn't pass that deal up.
Now to try to plan out how I want it to look.

Now as far as drainage goes, do you think the plastic -- whatever its called -- thingy in the bottom would be sufficient?

This terr will only have plants -- mainly orchids -- in it. In my 30 gal [which will be getting torn down as the 90 gal is its replacement] I have an inch or two of primagra [the puffed clay balls/pellets]. If the plastic ?grate? would prove sufficient I would be happier just sticking with that. [Would keep the tank lighter which would be great when someday I move out of my 3rd floor apt. Heckuva lot nicer than tearing the sucker all the way down.]

Are you trying to make a false bottom, where you use egg crate on top of some permanently placed pipes? If so, that is enough.
Just make sure you raise the plastic at least two or three inches from the bottom. Also you will need to find a way to drain all the water that ends up down there, either by drilling a hole into the tank (I don't reccomend it as it might be tempered glass), or by leaving some of the water exposed so you can siphon it out when it reaches too high a level.

With the leca, its the same deal, everything will possible stay even more moist than with a false bottom.

By the way, NICE FIND!!!!!
