Roughly 30-40 lbs of CaribSea LifeRock! Open boxes! This is what I didn’t use that was donated to me. The funds will be used towards maintaining a saltwater tank at a school. This retails for over $200 so it’s a great deal. Pickup only in the Lehigh Valley Area! I will also accept a $100 gift card to Something Fishy or Bulk Reef Supply and possibly trades.
