starting bio-pellets: how should i build a good bacteria base?

[The Grizz]

Hold off on the pellets until the tank is at least 6 months running, just my experience. I use the Vertex brand and have been very happy with them. About a month ago my sand was turning a copper brown color, I knew I was getting low on pellets in my reactor. Topped it off with another 1000ml & within a few weeks the copper brown color was gone.

When you do start pellets start with half the recommended amount for a couple months. You won't need a lot in that small tank.
