I'm going to toss my two coppers in here...

I've heard plants are great food... for supplemental use, though! If you're going to be away for more than 3 days, you probly should have an automatic feeder, or those disolving tablet things for your fish.

Plants are good for them to nibble on ever so often (they eat the plant itself, and diatoms off it), but it shouldn't be used as the whole source of daily meals.

And yes, if you take care of them properly, they won't clog the filter (I had Hornwort die and it's shedding leaves clogged the filter, but my Anarcharis is healthy and doesn't shed at all). In fact, they help the filter...plants like Nitrates, which bio-filters don't catch.
