Quick Overview

Tonga Jumbo 30"+ Shelf Rock has a minimum diameter at its longest point of 30" or larger.

Sold by the Pound - Minimum order 40 lbs

Unable to ship to Canada

Jumbo 30"+ shelf is, 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. For jumbo pieces, please specify your request in the comments area during checkout. We are unable to guarantee pieces with or without bases over 20 inches. Customer service will contact you for more details if required.

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.

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.

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


Full Details

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 apitasia, 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.


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. Please note that all Large 30" + Shelf Rock will have a diameter of at least 30" at its longest point.


Shipping: Tonga Shelf can be fragile. BRS makes every effort to securely pack the Tonga Shelf. However, we have no control how UPS handles it and it may break during shipping. Unfortunately, this is not covered by insurance so we are unable to replace broken pieces.


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.

  • not good...don't buy ...not likethe pictures By Michael on 5/15/2017

    This is the worse "shelf" rock I've ever seen...It's nothing like the picture...basically heavy slabs of concrete that is so heavy that you have to pile a ton of rocks on one end to "cantilever" in out into the tank....I didn't get one stem like the picture shows...however I used a tube of epoxy and putty and could never get the heavy rock to stay...too thick and too heavy for use...these will probably just go to the dump. very very disappointed....
  • Unbelievable By Gregory on 10/14/2016

    Two rocks and my 125 gallon AquaScape is done!
    Resulting in the best looking AquaScape I could of ever hoped for.

Product Questions

Roughly how many rocks would 30 lbs be?
Question by: Mike Swindle on Nov 6, 2016 9:56:00 AM
Hey there, great question! This rock has a minimum order of 30lbs for a single 30" wide shelf piece. 30lbs would be only one rock in those dimensions. :-)

I'm setting up a large reef. 200 Gal. Why and how should dry rock be installed. I keep hearing about an acid bath . Exactly what is that? And is it necessary.
Question by: Tom Boyle on Nov 14, 2016 8:06:00 AM
Great question! An acid bath is a common procedure to help accelerate the decomposition of any dried organics that may be left on dry rock harvested from the ocean. Although proven to be effective in the hobby, we recommend a more natural approach through the process of a 4-6 week curing process. RT demonstrates that and answers many other questions related to curing rock in the video link below! :-)
