What kind of filtration do you have? Perhaps you need more, if there is stuff floating and landing on plants. I went from one AC50 on my 29 to two AC50s, and there were still particles floating around, which drove me crazy. Upgraded to a canister filter (Rena XP2), and I was much happier.
Is your water tinted by tannins in the water? Larger or more frequent water changes might help. I never bother with carbon, but that will also help with water clarity. I have heard of concerns about carbon removing nutrients plants need, but I don't know if there's anything to that. I've never used it myself, but a lot of people with planted tanks swear by Purigen.
What kind of lighting do you have? Are you fertilizing? Using co2?
Sorry to pepper you with questions, but knowing more about your setup would make it easier to address your concerns.
