If you are interested in using bioballs to reduce the strain on your LR, you need to cycle your tank using bioballs BEFORE introducing the LR. That means getting water flowing over the bioballs and introducing some kind of ammonia source (like a raw dead fish from the grocery store - stink is probably unavoidable). Watch the cycle progress (ammonia,nitrite, nitrate)...then remove the fish and add the LR.
Then you monitor the ammonia,nitrite and nitrate and do water changes as necessary to keep those levels as low as possible.
Over time, you can remove the bioballs from the system. Remove maybe 1/6 every week.
Unfortunately, the LR from LFS has usually made very long trips from the other side of the world. The best you can do is time your pickup to match the day they get it.
