thanks for the advice, i was under the undersytanding that bottom feeders ate the fish wastes. good to know, none the less, i couldnt tell you what my specs are right now, i need to get my own testing kit.

Here's a useful hint that I think everyone should know: Most LFS will test your tank water for free. Just bring them a sample It will at least give you a baseline.
