Can lava rock provide a beneficial bacteria if I add it on my tank?
Just like bio rings but a lot cheaper. Home depot has bags for dirt cheap. Just do your water changes normally and rinse it out in the tank water that you take out.
I have lava rock as decorations in two of my tanks. I love it. In my puffer tank, I have a few large rocks piled up with an air stone under it therefore causing water to move around it. It seems to work well that way.
It would grow just as fast as any other media you add to the tank but it’s porous so it can hold a lot more bb for less money.
Yes, it works extremely well actually.
And it’s cheap and you never have to replace it.
