For me, "staying on top of it" never works (4 dogs and a baby are distracting!). With an inch deep bed, I'd probably get some larger Nassarius snails (J&L has these) and maybe a sand sifting star. And maybe a conch. I just added these to mine, and they do a good job. Well, the wrasses help too, they mostly keep the entire sand bed in suspension. If you're afflicted with OCD at all, maybe skip wrasses :)
