You need to be careful with oyster shell. It will compact down to a very hard 
substrate and can be a bit sharp to the touch when you try to uncake it.

You can also put oyster shell flakes in your filter if your looking to raise
the ph (put them inside a panty-hose leg and tie it off). They sell the
oyster flakes at feed-grain stores. From what ive heard you can also just
put it directly in the tank under a rock. They sell bags at feed - grain
stores as it is used for chicken-feed supplicant. Someone on craigslist just
gave me a bag for free.
