- I've heard dolomite doesn't quite hack it for keeping the pH up. I use a
- mixture of crushed coral and dark gravel.

-
- Go to any hardware store. It is sold in 2x4 foot rectangles for use in
- suspended ceilings as a lighting baffle.

-
- Go to a rockery. Any of those places that specializes in large quantities
- of rocks. I picked up 150 pounds of alpine green granite for .20/lb. If I
- had known how much algae would grow, I would have gotten the cheaper stuff
- at .05-.10/lb instead.

- I like you guys' ideas on this. I don't use an UGF with my Africans [N.
- lelupi, N. "daffodil", N. savoryi, J. marlieri], but am worried they might
- start digging out under the rocks now that they're bigger. I'll put
- eggcrate by itself covered with gravel on the tank base so the rocks wont
- crack the glass if they hit bottom.
