Review: Great product - We were very skeptical purchasing this product, based on the reviews, but we tried it anyways. We have purchased a few times and every time we have been more than satisfied. The box seems to contain more than the advertised 5 lbs. There is a nice selection of big and small pieces, fitting for building towers and productive landscapes. Just ordered another 2 boxes. The price is right. Rinse it well, there is dust due to shipping. It is a good product. Thanks.
Review: Great to work with - The pieces are nicely shaped and easy to bust up into smaller ones if necessary with just a hammer's tap. Your imagination and aquarium epoxy is the only thing you need now to make some interesting shapes.

## Questions & Answers

**Q: What kind of sand will i need**
A: I think you should google "how to choose aquarium substrate".  I'm far from an expert but many factors go into choosing like: is your tank freshwater or saltwater, do your fish need to burrow, do your fish like to sift the substrate, are you going to keep plants in the tank. Once you set up a tank, the substrate will probably be the hardest thing to change. Good luck!

**Q: How much & big is 5 lbs?**
A: I’ve bought about 5-6 separate 5 pound boxes. 
Each box holds about 5-7 medium size rocks. 4-7 inches in size. Great rock to scape with easy to work with.

**Q: Is this real limestone? Im hoping it will help raise the ph and harden the water in my aquarium**
A: Yes, it's oolitic limestone, they just cut it to make the stax shapes.

**Q: How many boxes are good for 12 gallons?**
A: If there are no other rocks already in the tank, I would use 2-3 boxes.  It is better to have extras than look barren.  I supplemented my 55 gallon tank with just one box but I had four large rocks in already.

### ⭐⭐⭐⭐ Great Rocks!
*by V***A on May 8, 2025*

Bought 5lbs to try in my Fluval 13.5 tank loved them so much bought 10lbs more. 5lb box was packaged with extra care causing minimal breaking during delivery. I only wish the same care was used to package the 10lb box but I was still happy with the contents.
