Refilling Pellets: What brand should I use?

[thebanker]

Need to top off the reactor, it's been about 9 months with Vertex, so far so good. Would you guys add more of what brand?


Vertex
TLF <- Leaning this way because of their rounded shape.
Brightwell
NPX Biopellets


Not an option (too many bad posts about these):

Warner Marine
BRS

I'm using vertex and Wm and the both look exactly the same.

I know. From what I can tell there are three pellet-looks.

Vertex, warner, and BRS have the "cut cylinder" look.
TLF are small tan oblong spheres
Brightwell look like small lump "biscuit dough balls" if that makes sense.

So far, they all seem fairly similar in the way they work. User experience is limited, though.
