Rather than tearing down the tank again, I was thinking of scooping some sand out from the surface and putting gravel back over the top. I want to keep some Amazon Sword, Egeria Najas, and Wisteria in the calmer sections.
Q1. Would this work or would I be faced with a cloud every time I vacuum the gravel?
Q2. How thick would the layer of gravel need to be? ie. Thick enough to stop the sand stirring up yet thin enough to vacuum in the bare areas.
