makes fragging easy
I used these rocks to build a tower for my devil's hand coral. Easily arranged and epoxied together. Nice coloring. Would work great for fragging.

Beautiful rocks for anemone tank.
It leave a pink residue on hands when cleaning the rocks , I think it shouldnโt thatโs why 4 starts , they are beautiful rocks. Below a picture of 2 bags 2.5lb on a 38 gal fish tank (30x22.5 inch), waiting for a second delivery of bigger rocks. Edit: two months later, color became just dustโฆ a lot of dust, still my crabs doesnโt care but my starfish avoid those rocks .

Great if you're a DIYer
Great product especially if you like DIY stuff. Bought 2 boxes and created a nice rock formation for my Clownfish and emerald crab. Created a 3rd with the leftover rocks. I also bought 4 starter corals and mounted them. Great value for the $$$$.

Perfect for fragging and placing frags!
There are plenty of rocks in the box. All are similarly sized. They are perfect if youโre fragging. I clipped frag plugs off of my degas that just arrived, and glued the discs onto these rocks. I was able to create a few islands, and glued a few of these little rocks onto larger pieces of live rock.

Small stones
A relatively small box of very small 1-3 in stones. I see no value in buying this, and the price is very high for this type of item.

Frag Rock
Frag Rock arrived, colouring comes of very easily so will have to see what that is like (perhaps normal for this type of product) when used, I've not added to tank yet, I'll be checking my water closely once added and will update the results.
