good to hear bastard, I really think you will like them. And my water line is right up under the nets. 1/8 inch or so below. In this cloner i have 4 air stones in it. its a tiny pump hooked up to a 5way. wasnt getting the splash do to the type of stones I use. they are great for millions of tiny bubbles but not good for big splashing ones. different stones are better and you dont need as many, but had these left over from when I was runnin a rdwc system. water is roughly 1 1/2 inches below the lid. its a 10gal rubbermade storage bin. like 3 bucks at lowes.
