LANDEN Elephant Skin Stone Natural Multi-Texture Rocks (18lbs, 3~9 inches,7pcs) for Aquarium, Paludarium, Terrariums, Landscaping, Decorative of Caves, Waterfalls, Cliffs

I bought two orders of these for my new 75g aquarium and would love to give them a solid 4 stars, but 3 of my largest rocks would NOT sink! Unfortunately it wasn't until I added water that I discovered this. So, be prepared to either test the sinkability of each rock before you set up your hardscape, or glue everything in place before adding water. I tried for weeks to get them to sink with no success, drilled tons of holes in them, soaked them for more than a week, I mean these things are bouyant! Lol Other than the three I wasn't able to use the rest look great, and overall I'm happy with the purchase. I do feel that if you're selling something for aquarium use it should be tested before it's sold to make sure it will actually stay in an aquarium without a bunch of extra work.

Long travel to Colombia southamerica, every stone was wrapped in foamy paper, less than 1 oz in debris which was surprising.I placed one of the stones inside the 8gal tank at 60% light to see color change (first pic). Very pleased with Landen products.Second pic fork for scale.

Landen is forever more my go to seller for aquascaping stone. For the money this is the best purchase by far! They delivered lava stone way beyond my expectations. Lava stone was individually wrapped and packed firmly. I really appreciate the care and customer service. I could not be happier. Thank you!

beautiful large rocks more than enough to scape my 29-gallon aquarium.

The stones were assorted pieces, well packed and ready for the tank. I soaked them for a few minutes to remove any residue. They create a very natural looking environment

Purchased the red lava stone and very happy with the quantity I received. They were all in great shape and plenty of different sizes. I let them soak in a bucket (with a few water changes in between) for about 2 weeks. Once added to the tank and filled, water stayed clean.

The rocks came in a perfect variety of sizes and look beautiful. I gave them a good rinse and scrub with a brush and they were ready to go.

Black lava rock is a must. Bio media and looks great!

Superbes pierres et de toutes les tailles. C’est ma 2e commande et aussi satisfaite. Très beau résultat dans mes terrariums.

So happy with my purchase. Arrived by Canada post earlier than expected. 3 large pieces that are bigger than my hand, quite a few med and some small. They do need a super good clean but I was expecting that. The box said 16lbs but weighed it and was closer to 17lbs. Highly recommend

The media could not be loaded.  These rocks are simply stunning. Look soooooo good in my shrimp tank. Didn't spike any ph or anything. I love them so many different sizes, I got 2 huge ones and 5 smaller to mid size. Love, love love them. Highly recommend them. You won't regret it . Came next day.

There were so many pieces which made it great for hardscaping my aquarium. I bought 2 orders. Came promptly in great packaging. Thinking of ordering again to add some more.
