If I start a cycle (100gal) with 60lbs Cured LR and LS and DSB fuge, should I just get the cheaper LR so I don't kill all the inhabitants of the really nice LR (LiveRocks.com stuff for example)? Also is it really beneficial to start cycle with bacteria booster for LS or just let nature take its corse? There are some nice kits at IndoPacificSea Farms.
