I have a few empty containers that coffee grounds come in when bought from the store (they are plastic). There is a combination of Ranid (Lithobates pipiens) and Hylid (probably both P. triseriata and P. crucifer). Should I use bubble stones? I don't want to agitate the water too much, and my air pumps air a high rate.
