I personally have never used the glass rocks, only because I'd be afraid that Sheba would eat them (of course, she is a lot bigger than Cortez!). Rocks I have used in the past with a lot of success: granite (hard & colors vary from pink/tan with little dark gray specks) & quartz (also very hard), and any other kinds of river stones which have been tumbled & are very round, preferably the ones without layers because sometimes the layers can sometimes come apart in the water.
I have also used in the past with great success: broken pieces of brick to prop up a basking area when I had smaller turtles or broken piece of cinder block (sometimes you get a nice big flat piece to put on top of the brick). The nice thing about cinder block is that it has a rougher texture which makes it easy for the turtle to grab & pull herself up.
Don't worry about rough edges on the rocks.....turtles deal with rough edges in the wild too & have no problem navigating around them. The only one who has to worry about rough edges is you, when you reach into the water or clean after them!
I never had to pay for any of the above rocks. They were all free, thanks to some guys at various construction sites who were more than willing to give away their broken materials.
