CaribSea South Sea Base Rock - 10 lbs - Natural Aragonite Rock for Aquascaping, Promotes Coral Growth & Enhances Stability in Marine & Reef Tanks - (Case of 3)

These rocks are amazing for the price. Bought two boxes for my tanks (10G and a couple of 5 G) . I still had a few left. good size rocks, generous quantity. will definitely buy in the future when i upgrade my tank!! Make sure to wash them thoroughly before dropping them in the tank. They are pretty dusty.

This is amazing value for your $ - comes pest free, and is easy to work with. I got three huge pieces, that were fairly easy to break with a hammer and flathead screw driver. I was able to create a great piece for my 3g Marineland contour with this rock. It is great rock to be able to work with, safe for your tank (whether SW or FW), and I prefer over anything. If you have a smaller tank, you will definitely need to break it up, as it looks like boulders when you first receive. Don’t let that discourage you though. Just make a mental pic of what you would like to create, and you will have a master piece with a little vision!

Received today and bought 20 poinds and although it was lighter than i thought it would be, i got an assortment of sizes and shapes. The rock is beautiful and arrived in great condition. I bought a masonry bit to drill them to insert fiberglass rods in them to hold them together in my reef tank, but they are so porous that i am not sure i am going to need to drill them. Looks like there are several holes thay i can slide.my rod into (lol). Wont know until i get a chance to work on the aquascape, but overall very satisfied but wish i would have only gotten 10 pounds, because it seems like more than i need. The right line of rocks below is one 10 pound bag and the left is the second 10 pound bag. A few little pieces broke off, and some dust. I threw the dust away and kept the little pieces that broke off.

The rocks arrived with no packing materials, just rocks thrown directly into a cardboard box. A few rocks were broken on arrival but you don’t get any say in what they look like anyway so it didn’t matter to me too much. The biggest rocks were about softball sized and the smallest were slightly smaller than baseball sized. All of the rocks have interesting occlusions but every rock has an overall round shape to it which I think is boring and makes it hard to create an interesting scape, especially with such similar sized rocks. I rinsed the rocks very thoroughly but because of the poor shipping conditions, chunks kept falling off and there was a lot of powder which made for a messy process. I added all the included rocks to my 6gal pico reef and it filled out the space well. This is probably my fault for not understanding live rock but it caused an enormous ammonia spike after adding the rocks, so be aware of that. I’m all for supporting my local fish store but for my first salt water tank I didn’t want to spend a fortune on it and it turned out well. These rocks were a good addition and I’d recommend them to someone trying to dip their toes into the hobby. Just be aware that this is a very cheap solution so set your expectations accordingly!

I purchased 4 bags (~ 10-11 lbs each) and each piece is beautiful. The bags are made of heavy-duty net and contained between 3-4 pieces each. The box had no padding, but I still had very little rubble (any small break-offs will be perfect for my sump). I used a toothbrush to help clear out some of the hard to reach places while rinsing. Be aware that they are kinda rough on the hands, so I recommend wearing tear-resistant gloves when handling. There are a lot of nook and crannies and the shapes are what I would have personally chosen. The shipping was fast. I live in Alaska and things generally take a lot longer to get up here. Pretty much everything is more expensive, so finding this item at such a great price was awesome! I haven't placed them in my tank yet, but may update this review later.

These are Awesome! Used in my 20 gallon High with Freshwater Angelfish (for size reference). I followed advice from another review and rinsed really well then let it sit 24 hrs with seachem prime (or any conditioner for tap water) in separate bucket before adding to tank. Color is great, came with many pieces to build my little structure! Alot for 10 lbs , Great deal and quality!

I am very happy with my rock 9 pieces 10 if you count a tiny tag along 😅 I am so happy with my purchase. The rock looks amazing in my 55 gallon i haven’t put my fish in yet but it’s looking amazing with my drift wood 🥰

Nice sized pieces that can be glued together to make much larger structures, lots of holes ect , wash before using it is gritty from handling during shipping, I would buy from them again.

Muy bonita piedra.

Great quality rock, came in mostly bigger pieces which is nice because it affords you the ability to break the rocks and manipulate them as you would wish. My local LFS was out of dry rock so I figured I would give it a go ordering this product and I was concerned about the selection of shapes, however I believe they do put effort into giving you a broad selection of shapes. Will likely purchase in the future if I am in the same situation. Did not weigh the bag of rock however I believe it must be just about on par with the lb per ga ratio as the picture is of a 10g tank
