Well, it wasn't in the pool til I cleaned the filter. Then it was in the pool immediately. It's not dead algae, as far as I know. It's been a couple months, and it immediately clouds the pool the minute I stir it up. It's greenish now, but it used to be more-or-less white.
The strange thing is that I could swear I saw it spouting back into the pool the minute I put the DE in, much faster than the water actually goes.
===========================
BTW, this equipment is dead simple. Just off and on. If by a mis-oriented valve, you mean one of things on top with multiple settings (I have one of those on our pond), it's not that.
