Used a real good dose on the algae in my pond. Not at all deep. Algae survived, I'm out $$. Used a surfactant as well and still nothing.

I like this shampoo because it keeps my pitbull from drying out and he has really sensitive skin. It also seems to keep him smelling better longer than any other shampoo have ever tried.

Program is about as user UNfriendly as you can imagine. It arrived without user manual and that's bad because this appears to be about as simple to figure out as a Rubik cube. It has the busiest screen as I've ever seen with many, many buttons, check boxes, and obscure links. It is NOT user intuitive!!!
