worth every penny Nov 15, 2014
I bought 25LBS last week, I just open the box and I am happy. It is the type of rocK I was looking for. It is very light and full of holes, all I did was rinse them off and place them in the tank. I just bought 25LBS more. I hope this was helpful. Thank U.
Never had a problem with this rock what-so-ever. Apr 15, 2020
I have ordered this rock 5 times now and every time it comes well packaged and on time. The rock itself is great and looks really good in the aquarium. There is a good assortment of sizes from large to small included.
Great dry rock Jan 5, 2020
I have had zero problems with this rock. Its all uniform in texture and appearance, comes in many different shapes and sizes and looks great in your aquarium.
Very Nice Mar 23, 2015
Picked up 25 pounds of this along with 50 pounds of uncured Fiji to star cycling my tank. Got a lot of nice large pieces. Looks nice along side the Fiji, even though the color is different. Hoping some of the coralline algae on the Fiji start growing on the dry.
