Bagged
LS is an absolute waste of $$ and leads a hobbiest down the "garden path" so to speak. If your going to pay any money for something like that, I would follow
hisc1ay's suggestion on aquiring something from an established tank. Just be sure the tank being "borrowed" from has never had copper or other meds in it. Another suggestion is Garf Grunge.
When first starting up a tank and using
LR there is absolutely no reason to buy anything but dry dead sand. The
LR added later or even near the start will do all the seeding you need. If using dead base rock then I would look to sand bed activators not bagged wet sand. Even in a
FO system, a dead cocktail shrimp would result in the same end results at less than ½ the cost.
Remember in
SW aquaria, fast = failure
