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.
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: 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.
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.
Great bang for the buck By Dodgersfan on 10/16/2017Dodgersfan would recommend this product to a friendThis stuff is incredibly light and porous, i ordered the minimum (15lbs) and got three great pieces just the size i asked for.
Better than I hoped! By BilbosRing on 8/24/2017BilbosRing would recommend this product to a friendJust received my order today. I ordered 15 lbs as I wasn't sure what to expect the mushroom look of the piece is beautiful! I also got a salad plate size piece as well. I am very pleased!
Tonga Reef with Base? By Mark on 8/18/2017Mark wouldn't recommend this product to a friendI'd like to start that I have been very happy up to this point with BRS products and customer service, but this warrants a thumbs down review.
Got my rock and there was no breakage. I had ordered 15lbs of Tonga with base. One had somewhat of a base, the second was a large flat piece of Tonga shelf only. No base, nor broken off. I am disappointed as if I use this piece I will have to re-think my aquascape. Nothing like the picture.
Absolutely the best!!!! By Roger on 8/5/2017Roger would recommend this product to a friendI asked for a piece that had more weight on the base that the top. Man did BRS deliver!!! They sent one piece that was identical to the pictures on the site. I am so pleased! This will be a beautiful centerpiece for my tank. They also sent another one that was very light on the top with more base that I will be able to use also. I bought extra weight than the minimum thinking I could whittle it down if it were too big...no need both pieces will fit. BRS went above and beyond my expectations. I would recommend this to anyone.
EXCEPTIONAL! By BRian on 7/25/2017BRian would recommend this product to a friendI didn't get extra weight like some have mentioned... but what I did get was exactly what I asked for. I ordered 30lbs and asked for them all to have good thick bases. I plan to use 1/4" acrylic rods to pin these to other rock structure so the bases were important. I got 5 really great pieces... I wanted to get a couple extra over what I wanted to have the ability to choose the best one or two to put in my display... now I want to put all 5 of them in.
I'd buy these again any time. Truly exceptional pieces.
As always BRS rocks!
Also great packing... not a single piece broken and to my door free in 2 days!
Great Rock By Edmund on 7/24/2017Edmund would recommend this product to a friendI asked for a nice rock to be center of my aquarium and got the most incredible rock ever! Very well packaged it arrived in perfect condition. Thanks you so much!
Amazing rocks! By JEFF on 6/8/2017JEFF would recommend this product to a friendAs soon as I got my package I knew I've gotten more than I paid for. I only ordered the minimum 15 lbs but the box felt like it weighed twice that! Box was filled with packaging styro but when reached in for the rocks, I felt a couple of pieces of rocks Inside the bag, my heart sunk thinking my rock had broken into pieces. To my surprise my shelf rock was not only intact but it's absolutely beautiful! Not only that, they also included another tiny shelf rock! I'm very happy and will order fromBRS again!
Not anything like I expected By michaelryer on 5/17/2017michaelryer wouldn't recommend this product to a friendWanted a centerpiece for my 55 gallon reef tank...first off, they looked basically like slabs of concrete...way too bulky or heavy to be of much use as a tonja shelf...secondly, there was absolutely NO STEM....waste of money....sorry...want to be honest...one "shelf" piece actually was so thick I ended up using it as part of an upright wall....won't be buying from here again.
Great piece By Kenneth D on 5/4/2017Kenneth D would recommend this product to a friendOrdered a piece 14-16" across to accommodate a large ritteri anemone. They sent exactly that !! Nothing broken and a nice little "neck" under the shelf to cement some pieces of dry rock so as to raise the overall height. Very impressed with the rock !! A+++
Very Generous By Joseph on 4/1/2017Joseph would recommend this product to a friendFirst of all, like everything else BRS sells, It was VERY well packaged. (now what to do with all these packaging peanuts....)
Second, it was 7 lbs heavier than i ordered. SEVEN! VERY generous!
I had told them it was to be the centerpiece in my tank, they obviously took this to heart.
Unfortunately, it had no attached base, there was a second piece which i assume they included AS the base, unless it broke off in transit, which it doesnt look like this was attached to it.
Thats the only reason im giving it 4 stars instead of 5. Nothing superglue cant do lol
Overall, AWESOME piece, it really IS the centerpiece to my tank. Thanks to all of BRS!
Big beautiful pest free workable rock By Old Hippie on 3/21/2017Old Hippie would recommend this product to a friendLarge, I damaged pieces. Very generous with weight and packaged well. Drill it, carve it, and get creative as the dry rock is workable and can be glued together very strongly with gorilla glue for great creativity or if you break it. Also aptasia free!
Where's the base?! By Doug on 3/12/2017Doug wouldn't recommend this product to a friendLooks nothing like thi pic. With that said, this is the only thing I've ever ordered from BRS that I haven't been satisfied with.
