1. Maybe. Id try a quarry and just wash it. Getting from home depot it would probably have chemicals of some type on it. And its free from a quarry or creek
2. Some sticks and branches I found walking around in the woods that I liked. You bake them to get out any bad stuff. Wrap them in foil and bake it on low for an hr or two. Anything over 170 degrees f will kill bacteria.
3. If u look on randomzoid's profile I think he's got texas holey rock in his mbuna tank. You like white? Its very white, lightweight and very pretty. He has a featherfin in his tank too.
You should cycle quickly. Lots of bacteria in the driftwood and decor too
I measured, it's big enough. On a side note - I ran into an old buddy who now works at a glass shop earlier. They do everything from big windows on buildings to auto windshields. Bout to get awfully awesome in the world of max's fish tanks lol
I'm going to try and talk them down on the tank if I buy the stand too. They were $10 more than the lfs but the lfs tank came with a ugly black stand but also offered 20% off thier ridiculously price accessories with purchase of package and all I really need is another heater
