Live sand and Live Rock questions

[scuba-raru]

I have a 10 gallon Aquasystem tank, I just bought it from a friend who had it for 6 years, the substrate in in right now is crushed rock, I want to change it out for some live sand, how much do I need to create a good sand bed? What kind should I get?
In the tank I have:
1 percular clown
1 bi-color
2 anemones (1 large one and one small, a division of the large one)
2 Turbo snails
I was also wondering, I have a pretty bad aiptasia problem (im combining lemon juice injections and also adding some peppermint shrimp for that) and am replacing the substrate for that reason also (I like sand better anyways), I plan on adding all new live rock too, How much can I add, and what size rocks do you all recomend?
Thanks for the tips,
R.

Around 15 pounds should do you fine for live sand. Might want to go for 20, but I like a deeper sand bed personally.
Couple of peppermint shrimp will take out that aptasia pretty quick, you can also try using a syringe to shoot kalk water directly at them, but do that with caution. Might want to find someone who has done it, and as for the exact procedure on it as I've never had to do it, only read about it.
The rock size doesnt really matter, that's just a matter of personal preference. I'm going to be setting up a 7 gallon next week, and I'll be looking for 2 good size pieces around 3-4 pounds each, and a couple of smaller pieces for filler. You can go for around 15 pounds no problem.
