[I]clear as in clear of algea (for the existing ones). and down and under water because they will shoot out water, you want them as close to the water line as you can get them, while still being submerged. if they are out of the water they'll be noisy, possibly make bubbles down in the tank with their stream of water.</em>
Now it makes sense. Thanks.
