Lava rock or coarse gravel?
I need to build up the base of the rear half of my tank and lava rock sounds like a popular option. However, I'm wondering why plain old aquarium gravel wouldn't be a good option as well. Does it come down to weight and cost? I would put the lava rock or gravel in mesh bags for easier handing/positioning. It seems to me that gravel would give me more flexibility since it is much finer, but I'm not sure how much this actually matters since I'll be filling any voids with aquasoil anyhow. I like that the lava rock is light weight, but don't like that it's red in case things shift around and it starts to show (although I'll be using black mesh bags). On the other hand, I like that the gravel is black and more maneuverable, but it will add significant weight to an already heavy tank (I'll be using a bunch of elephant stone). Perhaps I could use a combination of both--lava rock to build up the higher areas and gravel for the lower areas. Thoughts?
