How do I keep my tank a little more clean with a Bristlenose Plecostomus around?

I got her two days ago, and I've never seen so much poop in my tank! From one Pleco? Grrrr. So its my first algae eater, and I had no idea how messy Pleco's are. Its a female, because it doesn't have the bristles on its face. Anyway. Any tips on keeping it cleaner let me know.
