Here we go again, I was just sitting a little dazed and was trying to figure out what do I already own that is fish safe and allow the good bacteria to colonize on. Then it hit me, why not use the bio-balls that I'm no longer using.
So here's my ? Can I use bio-balls floating loose or place in a container and keep a flow at to get the good bacteria in my QT?
Yes.
