Tonga Shelf Plate Rock has come in many different sizes and shapes with no base.

Sold by the Pound - no minimum order


Tonga Shelf Plate Rock, perfect for overhangs, caves and holding lots of corals in large tanks. Free of nuisance algae and pests. Shelf with base pieces is more three dimensional than the flatter plate pieces. These pieces do not have any base or stem and can easily accept a small piece of rock to form a base or be added to an existing structure.


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.


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.

Product Questions

Could I use 1 or 2 pieces of this in an reef tank that is up and running or would it cause my tank to recycle?
Question by: Marc Holmes on Oct 9, 2017, 1:44 PM
Hey there,
Thanks for getting in touch with us in regards to adding this rock into an existing tank. This can be done, however this rock does have a lot of dead organics trapped within it that will cause your nutrient levels to spike. I personally would use water from my waterchanges each time to change out a 5G bucket that has a pump and heater in it to cycle the rock before adding it to the system. If you want something that you could add directly to the tank without and negatives I would use the product that I have linked below. This is a great natural alternative that is aesthetically appealing and contains no organics that will dirty your tank. Please let me know if there is anything else that we can assist with. Thanks!

Is it possible to get the shelf rock in 18 inch by 18 inch pieces?
Question by: Robert Benedict on Jan 26, 2017, 6:58 PM
Great question! Unfortunately, we are not able to provide custom rock orders. Although we can get as close to an 18" wide shelf piece as possible, if you order that 18" piece we cannot guarantee a piece that will be 18" long as well. :-)

Around how many pounds is a flat plate of 10 inches across by 7 inches wide?
Question by: Arlo on Dec 27, 2016, 7:41 PM
Hey there,
While it's hard to know exactly as there is some variation in plate thickness and density, I would expect a piece of that size to be around 4-5lbs.

Have a great day!
Answer by: Zack on Dec 30, 2016, 4:04 PM
Great question! That size of piece is going to be around 8-10 lbs. :-)
