I like "not" having to do thorough gravel vacs ever since I converted to a planted tank. Ditto on doing light "surface only" vacs to clear out any poop, uneaten food and detached foilage from the plants.
The weekly partial water changes (about 25%) are still a must. I think it's great that the plants can benefit from the mulm being dug into the gravel over time... makes for a more natural ecosystem.
