 So really, overall, it's probably a good idea, especially the smaller body of water, the smaller it is. If there's an algae bloom that's been posted, noted, you're probably better off just not getting in the water, period. Now, another thing, if people have, say, a decent-sized pond on their property, is there a way to prevent algae blooms? I know when I had a small pond in my backyard in the past, you'd get just plain algae, of course, being out in the sun, right?
