Lots of shapes and good pieces you can use to cement together

I got two large 10-11” pieces, 1 useless (to me) 8” round ball and a bunch of rubble. There are a lot of flat machined edges making the product look less natural. Took some extra finesse and customization but in the end I’m happy with my aquascape

This 20 lb order was exactly what I needed to get my old Biocube 29 stocked and running at my office. Quick rinse to get the dust out and it was crystal clear by the time I came in the next morning. I will be standing up my 100 gal reef tank later this Fall and will definitely be coming back for rock then. Thank you!

Exactly the same thing they sold at the local fish store for a better price. The 20 lbs I received will fit perfectly in my bio cube 32. Some of the huge pieces I threw on the ground to break up and get more sizes for aquascaping. But there was already a great variety of sizes. I just needed some little pieces.Soak rocks then rinse well (outside!). After soaking the rocks, I kept the plastic the rocks were shipped in and laid it on the grass to rinse the loosened debris.Pics show multiple aquascape ideas, the rocks in my box, and the silt that washes off the rocks after rinsing. Don’t put that down your drain!

Extremely porous base rock great for coral frags and creating biological filter. Easily stacks and makes for very appealing aquascapes. This rock is not cured, If you want live rock or even cured rock you will pay more. If you have a lot of time to cure this base rock it will be excellent material for any marine tank. If you want live rock you will pay more but really in the grand scheme of things not that much more.

I think this a great product. I got a lot of rock, all excellent shapes. Sorry the pic is fuzzy...sediment was still settling. I will agree with other reviews, it could be packaged better. There were several broken pieces in the box and several pieces that broke off while rinsing. I’m excited to watch my tank flourish.
