"Did buy again."

Com is the only place I trust for my tanks. It was plenty for the tank I wanted to scape. I had to break up some of the larger ones to fit what I was looking for. It looks nice, and my kids had fun choosing which parts to hot glue onto the rock. And placed in a 36 gallon bowfront. Not sure why but I just expected more. We are working on the hardscape for our new 36G bow front.

"Small but cute display."

I couldn't find these at any of the aquarium stores near me, chain or independent. I'm always hesitant to buy it online, but this was a good transaction. It was well worth time and effort to get them clean. Different shapes and sizes to work with. The shapes very interesting and pleasant to look at. I'm always hesitant to buy it online, but this was a good transaction. The bag I received was 17lbs and the rocks were in good condition.

"These are GORGEOUS."

Dragon stone has a nice reddish tone to it so it really stands out. Not sure why but I just expected more. Truly something unique that will appeal to any aquarist. When I keep it lit for at least an hour, it stays glowing for at least three hours. I love the look and color of this stone. Just trying to help you find good products for a good price. Would definitely love to repurchase this item.

Carib Sea 00381 First Impressions

"The fish love it."

Honestly not much more I can say about rocks. The water deactivates it and makes it safe. They match perfectly to my center piece and the cichlids love hiding in them. I also placed one or two inside her bathing dish to help her climb in and out better. It took about a hour to clean the rocks off. I soaked the rocks for about 20-25 min, took them out and hosed them off really well. Trying shipping this much heavy stone.

  • CARIBSEA INC Life Rock Shapes Natural Corral 20 LB
  • CaribSea LifeRock Shapes is made of an aragonitic base rock, instead of the typical cement used by some other artificial rock creators. Every rock contains a network of micro and macro pores that intertwine within the rock's internal structure, creating the perfect environment for natural nitrifying bacteria.
  • LifeRock is manmade. Every LifeRock from CaribSea has an artificial coating and texture that mimics natural coralline algae after being in the ocean for years.
  • Every box of Shapes LifeRock contains a mixture of arches, rings, and tunnels giving you unique looking pieces that can be used on their own or as accents to the rest of the aquascape.
  • Pieces are unique. They will look similar to the pieces picture, but every box is different. The Shapes will have 4 pieces: One cave, 2 arches, and one ring. We guarantee every box is at least 20 pounds. We recommend 1 to 2 pounds of rock per gallon of aquarium water.
  • NOTE: This rock is fragile and may break in shipping. Unless it is pulverized we can not replace the rock if broken. This rock needs to be glued together when placed in an aquarium anyway, and in many instances you might want to break the rock into smaller pieces to build a desirable structure.

"Overall, a good purchase."

Loved what I got, highly reccomend these. I got a nice large piece that was about six or eight inches wide. Don't even hesitate purchasing these stones. The structure is roughly 14l x 6h x 4d. Also, if you need any manzanita or any other driftwood. I'm always hesitant to buy it online, but this was a good transaction. Honestly it's a good idea to have some glue on hand anyways.

"I will be buying more."

My buddy said he found a better deal on etsy. I hate negative reviews for awesome items just because the buyer didn't read! Loved what I got, highly reccomend these. Really nice value for the money, I think. These broken bits are perfect for little details and filling gaps. The result is a beautiful black rock with white lines. So I bought these thinking I'd get much bigger pieces.

"She likes them."

The bag I received was 17lbs and the rocks were in good condition. I wanted a dark rock decoration for my 5 gallon. It's simple slate rock but it's natural and really great for my box turtle terrarium. Very surprised with how many rocks came with this order. Shipping was very fast and the stones were in excellent condition. Photo 3 is during a diluted muriatic acid bath. One bigger chunk and five medium chunks.

I've bought quite a few packs to get the volume I needed. Hope this helps anyone that was wondering how we got our rocks so dark. But it was definitely not what I expected.

"Would recommend!"

They arrived in tact and were all the size described. Hope this helps anyone that was wondering how we got our rocks so dark. It's not difficult but you need rinse over and over to get the water clear. They are making these by sloshing resin around in a mold, so it's really thin. I wanted a large stone to stand out from the rest. You should never buy rocks but there's no Dragon stone down by the river. I switched up my plans a bit and everything was lovely.

"Thank you!"

I wanted a dark rock decoration for my 5 gallon. It took about a hour to clean the rocks off. I couldn't find these at any of the aquarium stores near me, chain or independent. The only thing that was frustrating was the wait time for the shipping. Since it's 17lbs obviously you're going to get mostly small rocks. If you are still questioning your purchase please re-read the headline. I also placed one or two inside her bathing dish to help her climb in and out better.

"Be sure to rinse them."

I wanted real stone instead of the fake stuff at the local box stores. It's not difficult but you need rinse over and over to get the water clear. Photo 5 is a sample layout for my 45cm tank. No I dont work for them and no I dont get anything for saying that. It was plenty for the tank I wanted to scape. I had to break up some of the larger ones to fit what I was looking for. I am only giving 4 star because I had no way to request a larger stone after order.
