"Great for my betta tank."

Photo 3 is during a diluted muriatic acid bath. But then again, it's 17lbs of rock so I struggled rating this one. It took me all day to get them at least somewhat cleaned off. I got a nice large piece that was about six or eight inches wide. Bought 2 then I needed more so got one more. These are just what I needed to creat stone walks in my model railroad park. I couldn't find these at any of the aquarium stores near me, chain or independent.

WAYBER 208 Final Thoughts

"Overall, a good purchase."

When I keep it lit for at least an hour, it stays glowing for at least three hours. I placed an order of 10ilbs for my 20g high. I wanted a large stone to stand out from the rest. Also, if you need any manzanita or any other driftwood. The water deactivates it and makes it safe. After playing with them for awhile now. I thought the price was great for the quantity and quality as well.

"The price was excellent."

And I just realized they are using them to hide their babies. I love the stones, but yes, barely enough to cover a corner of my aquarium. I got several smaller pieces that were about four to five inches wide. No I dont work for them and no I dont get anything for saying that. The holed rock formation is a nice design, but the material being is way too thin. These are just what I needed to creat stone walks in my model railroad park. Loved what I got, highly reccomend these.

Small World Slate & Stone Final Thoughts

"No issues so far though."

They are making these by sloshing resin around in a mold, so it's really thin. These are just what I needed to creat stone walks in my model railroad park. Honestly it's a good idea to have some glue on hand anyways. They are worth very dollar, and a very good price. Different shapes and sizes to work with. I hate negative reviews for awesome items just because the buyer didn't read! The big rocks and theses small ones go perfect together.

"This was exactly perfect."

I really hope they upload the other 3 pictures. And I just realized they are using them to hide their babies. It's not difficult but you need rinse over and over to get the water clear. For the price, this should be solid resin. Great stones, came with 3 various sizes for the 5 lbs option. Shipping was very fast and the stones were in excellent condition. I am looking forward to getting my tank stocked up!

"These are kinda gorgeous!"

The shapes very interesting and pleasant to look at. These are excellent stones and a great buy for the money! Waiting in my second bag as I'm typing this. When I opened the box I was so surprised and shocked. The edges of holes are also sharp, but easy enough to smooth with a razor knife. Def need to clean before putting in your tank. My buddy said he found a better deal on etsy.

Hope this helps anyone that was wondering how we got our rocks so dark. My only problem is trying to arrange them. They are making these by sloshing resin around in a mold, so it's really thin. I will not be able to get all 7 rocks in my Bio Orb 8 gallon tank. I got this for my 10 gal and it fits beautifully! The bag I received was 17lbs and the rocks were in good condition. My cichlid love hiding under the caves.
