SO recently I got a 90 gallon tank I wanted to go with sand as a substrate because I've never used it and I like the look. I just did my first water change on it's long way to cycling. Sand is messy! Am I going to have to deal with a bucket load of sand and the cloudiness of the tank every time I do a water change? I'm only using a gravel vac and filter(of course) to clean it. Tips, or suggestions would be great
