Tonga Shelf Rock with Base, perfect for overhangs, caves and holding lots of corals in large tanks. Free of nuisance algae and pests. Shelf with base pieces makes great rocks for aquascaping and creating unique designs. The size and shape of the rocks, as well as the base, can vary from piece to piece.


BRS recommends curing all rock before being used in an established system


Like all of our dry rock Tonga Shelf is free of nuisance algae and pests which can cause complete tank shut downs and is guaranteed to be free of aiptasia, bubble algae, parasitic isopods, mantis shrimp, acro eating flat worms, little red bugs, fire worms, predatory nudibranchs, pyramidellid snails and other common pests.


Using Dry Rock has the following advantages:

  • Low initial cost on premium types of rock.
  • Pound for pound a way better value - no water weight.
  • Can be shipped standard UPS ground which saves a fortune on shipping.
  • Absolutely pest free. This is the most important reason. This allows you to completely avoid all of the most common aquarium pests that plague most aquarists.


How much rock do I need?

Knowing exactly how much Dry Live Rock you will need can be one of the hardest questions to answer since every tank and rock will be slightly different. A general guideline for Tonga Shelf Dry Live Rock, we suggest 1 pound of rock per gallon of display tank volume and may vary depending on your overall goal for the aquascape. We always recommend purchasing a little extra dry rock to ensure that you will have enough to complete the aquascape you are looking for, any extra rock can always be broken up and placed in your refugium, overflows, and sump for added filtration.


Rock Selection: Due to the wide variety of unique sizes and shape of this rock it is impossible to fulfill orders to exact dimensions, but we are happy to make every attempt to get as close as possible if you leave notes on what you are looking for in the order comments section of the checkout. Shelf with base will normally be a big heavier than traditional shelf rock considering the base or stem that is attached. The minimum order is 15 pounds which are the smallest Shelf with Base rocks that are available.


Picking: When ordering rock any notes for size, shape, or concerns can be left in the "Order Comments" field during check-out step #3. Our picking department will do the best to follow the notes on the order.


Shipping Notes: Tonga Shelf can be fragile. BRS makes every effort to securely pack the Tonga Shelf.  However, the UPS automation is not always gentle on heavy products like this, and they do not consider this product insurable. Because of this, there is some inherent risk with shipping rock like this across the country, and it is impossible to replace or refund broken pieces. If this happens most, pieces can be repaired with epoxy.


Note: Dry live rock is not available for shipment to Canada due to high tariffs. Please consider Reef Saver rock as this is not subject to these fees and our favorite of the dry rocks available.

Thanks for reaching out to us! Our Tonga Shelf can be ordered to the length that you desire. All you have to do is annotate the length needed in the comments sections of your order, and our team and pick those specifically for you. I do recommend accounting for at least 5lbs for a 4" across piece. :-)
