Hi, I am just accumulating all the materials I'll need and I'm not sure I understand the difference between gravel and sand. I realize that if I do choose gravel it must be large enough that my axie doesn't eat it, but if I'm not getting an under gravel filter I'll have to change/clean my substrate more frequently, no? Thus, using sand will be much more difficult. If you have any tips here, I would love the help,
Thanks guys,
Tim
