The small size measures 26.5 x 16 x 9.5 inches (LxWxH) and has a 17 gallon volume, and the large size measures 26.5 x 16 x 17.5 inches (LxWxH) and has a 32 gallon volume.AquaBlox are manufactured using recycled materials and designed to efficiently maximize your water storage capacity, providing the ability to hold more water with a smaller reservoir footprint.

Review: Very sturdy - I bought these to use on my Koi pond. We needed to cover it to prevent the kids from falling into it. We stacked them up and then covered the top with flagstone to make our pond into a pond less water feature… we left the bubbler and sump pump in place. Now we gave a water feature without the dangers of a pond for small kids or pets. The plastic material and pattern on the cages makes it pretty strong, we can walk on top with ease. These gave worked out perfectly for us.
Review: Koi shag shack. - I’m using it to keep water lilies at the right depth in my fountain/koi pond, and it’s perfect for that. It’s transformed my pond—my koi spawned! (Check it out—I’m a poet and I didn’t know it.) I guess all they needed was a little privacy.

### ⭐⭐⭐⭐⭐ Very pleased with the quality.
*by T***S on July 5, 2022*

I ordered this item to covert a pond/ stream to just an endless stream. Easy to put together and very sturdy! I read that some say it only goes one way, but per instructions you should have all 6 sides of the box supported. So, it doesn’t matter what side you place the box, just make sure your hole is snug, then used large heavy rock around it to secure the box. I was happily surprised it came with geotextile fabric too! The fabric was placed directly underneath the box and the RDPM rubber liner; original fabric is under the liner itself. Photo shows unfinished project before filling it with 2”-3” rock.
