🪸 Elevate your reef game with nature’s own architectural marvels!
Carib Sea Life Rock Arches are a set of four 12-inch porous aragonite rocks designed for aquarium aquascaping. They promote coral growth by providing ideal attachment points, enhance biological filtration through their porous structure, and maintain stable pH levels to ensure a safe environment for marine life. Lightweight yet durable, these pre-formed arches stack easily to create natural caves and tunnels without adhesives, making them a top choice for reef enthusiasts seeking both function and style.

Awesome Life Rock!
I got several beautiful arches and one big cave. They were packed extremely well, but one arch was broken. However that's not the fault of the company, I saw my mail person slamming the box on the ground (it is heavy). I was able to glue it back together and my reef looks amazing!

Amazing product
I am very happy with this product. The arches are nice provides a ton of coral, anemone, and fish spots. One small broken piece, I honestly kinda wish there were a few more broken pieces for the filtration! lol all in all money very well spent and if I set up another tank, 100% using caribsea again!

Great looking However arrived broken.
Great looking dry rock but arches were all broken when it arrived. The package looked fine when I received it but upon opening the box I noticed the two major arches were broken into multiple pieces. disappointing to get something broken. Takes a long time to cycle in tank as it's not very porous so don't expect it to be plug and play. Will eventually lose some of its color. Probably would buy again and add some epoxy to the order to repair the broken pieces.

PERFECT !!!! Beautiful!! Healthy for my tank.
This product delivers just as you should expect! I received many large pieces including arches, pass=thru holes and caves. Nothing was broken, just a couple chips.SO pleased !! I am setting up a 75 gallon tank and deciding to take the most organic approach possible without killing myself. So far real good!! I dropped it right in fresh out of the wrappers. No dust, no water fog and instant upgrade !! The look of this rock is stunning! It's instant reef !! Most importantly with no pest or algae infestation. Just INSTANT beauty and depth!! I understand there are many different saltwater paths I can take using this rock as the foundation. I plan on adding even more and introducing this to my 46 gallon Bowfront of 20 years. All the experts, pros and hobbyist were right.....this rock is a brilliant and safe addition to your marine aquarium for tank health and beauty.

Excellent value for the price!
Overall, I am SUPER happy with this purchase! There was a large variety of sizes and shapes in my box, all with lots of nooks and crannies which will be great for future inhabitants! I will say that several pieces had chunks broken off them from shipping, but considering the volume and weight of this package, it doesn’t surprise me. I can’t complain. The rocks still look great in my tank. I already had a decent bit of rock in my 55 gallon newly set up tank, as I transferred some live rock to it from my 32 gallon Biocube. So not all of this shown in my tank is from my shipment. That being said, I had four pieces leftover after arranging in my 55 gallon tank, one of which was very large, and I put those four into my biocube. The rock shown laid out on the table on the newspaper all came in my order. Beautifully colored pieces!

Packaged Terribly - Very Broken
Should have been a beautiful product, but packaged very poorly (heavy, fragile rocks wrapped in a single layer of brown paper and tossed in a box with ZERO other protection) and therefore arrived with every piece damaged. I've ordered LifeRock before and this is the worst packaging for this product I've ever seen.

Really happy with my 'display box' used for my first marine setup on 125lt tank, got 6 good sized and good shaped pieces, would reccomend. Colour looks good from the start. Abit pricey compared to LPS but no risk of pests is worth it!

Glad I purchased this rock,looks great I bought 40kg all the pieces were of different sizes. I have always used live rock in the past but got fed up with hitchhikers.

Delivery was really fast taking into account we are in a pandemic and it’s Christmas time. I live in Scotland and it arrived from England in 2days! The shapes look brilliant, I’m going to spend ages trying to aquascape as I have so many options! I’m really happy and would highly recommend

I received 7 pieces in my 20lbs order to my surprise! I was expecting only 5-6 pieces. Colour of the rock is fantastic. Good quality pieces for ease of Aquascaping!
