So my 20g tank has turned from being a show tank to a growout system/frag tank. I have about 20 lbs of rock and some nice sized chunks of marinepure in a hob filter. I would like to empty my sandbed to make it easier to lay down frag disks. Would it be okay to remove the entire sandbed at once or should I do it 25% at a time? Its extremely dirty stirring it up a little bit causes a black cloud. (This tank is rather neglected)
