I have the following pukani rock for sale. Around 20lbs. It is from BRS that was cured and cycled and has been sitting in circulating saltwater in a covered bin for the last three months. It hasn't seen any coral or fish since I bought and cured/cycled it and thus is completely pest free. It was cycled and seeded with bacteria at one point, but I haven't fed it a nitrogen source for at least two months, so it may or may not still be seeded with bacteria. Yours for $50. Pick up in Castro Valley.
