O.C.'s Pellet questions and answers!

[KPG007]

I have 3 sumpless tanks (2x 33g, 55g) and would love to try these pellets out. All 3 tanks currently have cannister filters attached to them. Has anyone tried adding the pellets to the cannister?
As a cannister has multiple compartments, can I also run carbon in there at the same time?

Thanks;
Kelly
