Quick question there is a water control valve that can be opened or closed that connects to my water pump. The valve is towards the top of the aquarium. If it's opened it exposes some holes where water can be sucked through. Should this valve be closed so water can only be sucked from the bottom or open. If open should it be open all the way or only part way. Thanks.
