How to make D.I.Y. bio balls
Hey guys I have a doubt about how I can make some bio media for my sump when I don't have enough money to buy the whole bio media. Do you guys have any idea on how I can make one as I have some very porous stone at this point and I wanted to make it into bio media. Is it fine to do so?- Aquatank
