"It wasn't horrible."

I switched up my plans a bit and everything was lovely. He hides in it all the time and so far he hadn't torn any fins. And I just realized they are using them to hide their babies. Worth every penny, my nano looks great. But it was definitely not what I expected. Worth every penny, my nano looks great. The rocks were REALLY dusty, covers with a lot of clay.

"This is just beautiful!"

Bought 2 then I needed more so got one more. My cichlid love hiding under the caves. 2 small rocks and 4 medium ones and one large stone. I may have even used too much rock but I love how the scape came out with this rock. Just hit the add to cart and wait until you get the dust off and see them wet. I was expecting this to be a thicker resin piece. The result is a beautiful black rock with white lines.

"I have 55 gal."

I am only giving 4 star because I had no way to request a larger stone after order. Super happy with what, only downside is I should've bought 2. I'm always hesitant to buy it online, but this was a good transaction. These are just what I needed to creat stone walks in my model railroad park. Great seller, great product, great price! The resin color is dark, so no repainting needed. And placed in a 36 gallon bowfront.

"Would recommend!"

My order came with large and small pieces allowing for some good combinations. Bought 2 then I needed more so got one more. They get tossed around in shipping and chunks break off. I switched up my plans a bit and everything was lovely. You should never buy rocks but there's no Dragon stone down by the river.

"I ordered 2 sets."

This isn't even all of them in the photo. I placed an order of 10ilbs for my 20g high. Shipping was very fast and even came early. My buddy said he found a better deal on etsy. I also placed one or two inside her bathing dish to help her climb in and out better. Dragon stone has a nice reddish tone to it so it really stands out. I am looking forward to getting my tank stocked up!

"So far so good."

And will change the hardness and ph of your water as it leeches. I will not be able to get all 7 rocks in my Bio Orb 8 gallon tank. Super happy with what, only downside is I should've bought 2. It was well worth time and effort to get them clean. The rocks were REALLY dusty, covers with a lot of clay. Love these rocks and you usually get 1 big, 3 Med and the rest small. I placed an order of 10ilbs for my 20g high.

"Its a fortune."

It was plenty for the tank I wanted to scape. Perfect size just what I needed not as many as I expected. When I opened the box I was so surprised and shocked. For the price, this should be solid resin. I had to break up some of the larger ones to fit what I was looking for. The best part about this product was that it came with additional plants. Trying shipping this much heavy stone.

"Nice big pieces of slate."

I hate negative reviews for awesome items just because the buyer didn't read! I really hope they upload the other 3 pictures. Every living thing in both tanks are healthy and as far as I can tell happy. My cichlid love hiding under the caves. Honestly not much more I can say about rocks. It's simple slate rock but it's natural and really great for my box turtle terrarium. You definitely get a lot of slate for the price.

"Recommended."

It's not difficult but you need rinse over and over to get the water clear. I love the look and color of this stone. When I opened the box I was so surprised and shocked. Just be prepared to buy several bags if you have a 20+ gallon. The water deactivates it and makes it safe. I've bought quite a few packs to get the volume I needed. If you see black substrate, that was still waiting for the 2nd bag.
