Get rid of the algae disc's.  Toss in a slice of Zucchini or cukes.  Feed him lettuce and spinach.  He is a veggie eater not a clump of white goo eater.  Chances are he doesn't even know what this stuff is.  Not all veggie eater especially pleco's won't eat these discs.  Really use fresh veggies to supplement his algae eating.

Remember don't clean the tank too well.  Leave the back wall with some algae.
