Driftwood won't sink. Any ideas?

My problem is the bouyancy of the wood breaks the slate. I have another idea:

1)Go out spend $10 on a marble tile (so it won't break)
2)get some longer screws
3)silicone the tile to the bottom of the tank.
4)then if required put rocks around it to hold it down.


My questions:
Do you think the silicone would be strong enough to hold it down. Is there a better substance to use (ie epoxy, etc.)
Can you drill through marble with a masonary bit?

Not to mention, do you think my above idea will work?
 
If all else fails, get a sheet of plexiglass from Homedepot,
the biggest size you can fit into the tank. Screw it onto
the peice of wood and cover with gravel. The idea is to
get as much gravel holding it down as possible - so the
larger the plexiglass sheet - the better. Just make sure you
can get it into the tank. You can also use some large rocks
around the tank as decoration, which will add additional
weight on the sheet to help keep the wood down.
 
If you decide to go the screwed into something heavy route, spend the extra 25 cents and get the stainless screws. No chance of heavy metals etc. leaching into the tank.
 
You might, as an alternative, try this:

Screw a wide piece of slate tile onto the bottom, say, at least 18" square. then, between the wood and the edges of the tile, place another tile like this, and screw it together.

So that you have a larger surface area to place heavy objects on.

Keep adding as many tiles as you can until you can manage to hold down the driftwood. Just a suggestion...

plexi-glass is kindof expensive. The idea of having a large peice of something on the bottom is a good idea tho.

Go to your local Home Depot and get a piece of LEXAN roughly the size you need. Then you can cut it to size with a power saw. And attach that to the driftwood

LEXAN is very sturdy and relatively inexpensive - it will give you more of the surface area you need so you can cover it with gravel, etc in the tank.

I read most of the post and the plexiglass idea would probably be your best bet. Is your tank already inhabited if not just put the heater full blast and wait then let the water cool. If you have fish it wont work. Another thing you could do if you dont have fish is to glue it to the bottom of the tank with alot of silicone (might have to call pamela anderson for the amount you might need) wait til it fully dries put ll the rock on top of it and keep your fingers crossed. Im glad I never had this problem my driftwood sonk like a rock when I put it in.
