never received this item. Petco has SKU number mix up so when you order this you get CaribSea base rock.

Do not order this product. The SKU numbers at the stores are incorrect and you will get CaribSea South Sea Base Rock instead of Rock Ledges. Happened to me twice even going through customer service.

TLDR: This item is sold as the Life Rock Ledges, but what you'll receive is the 7lbs bag of the CaribSea South Seas Base Rock. I placed two separate orders and both times, I received the same, incorrect item. Even when I went to return in store, when scanned, the bag of CaribSea South Seas Base Rock showed up on the register as "CaribSea Life Rock Ledges," so clearly there is an issue either in Petco's system with how the barcodes are assigned, or the bags are misprinted. Either way, you will not receive what you ordered if you get these online, which by the way is the only option, as every Petco location I checked was out of stock (I live in Los Angeles, so there are A LOT of them).

Item in store does not match the picture. When I went to pick up the order the rock was white and not flat like advertised.
