it's probably waste buildup from the plecs. that's a mighty small tank and not much of a filter for all those plecos.
i'd switch from the king's british pellets to the Hikari brand. unless you know for a fact that you have carnivorous plecos, then i'd just go with the Spirulina tabs (they've got a meat filler in them).
also, try adding some fresh carbon. that's supposed to help remove DOCs (dissolved organic compounds).
