Personally, I keep a 1/2 - 1" sand bed and I gravel vacuum it on every water change. I do this with client tanks too.

Agreed. When you add the new sand, use a 2 litre soda/juice bottle, fill it 5/6 of the way with sand and let it fill with tank water, then tip it up and let the sand filter out in the tank. As the sand flows out, any loose debris or sediment is filtered out and is left in the bottle. It helps keep the tank clean and allows you to direct where the sand goes. Just a thought.
