Hey Gary;
I can answer one of your questions since I am seeding my own sand bed.
If you don't have live sand see if you LFS will give you some or buy a little either on line or at the LFS. I am using some from my 29 gallon tank.
I have about 50+ lbs of southdown sand in a large container and I put water from a water change in the container added a pump and lighting and threw in a small piece of shrimp in there and I stir it a little every day(I used a wooden dowel).
In about 30 days your nitrates and ammonia should be gone and there u go, a live sand bed.
The first time I did it I bought about 25-30 lbs of
argonite sand I believe from petwarehouse.com
and it said on the package that it was "Full or Live organism" I did the process above and it does work. Good Luck.
You may be able to find southdown sand at Home Depot in the Garden center area near the packaged pebbles, blue and clear bag.
