Now that I have it I think it's more for commercial pet stores where nets are always being used.
Yeah, that's what it's used for, it's to stop cross-contamination between tanks to reduce the amount of stock lost to disease, we used it in the aquarium I worked in, we used to make up a big bucket of the stuff behind the counter that we kept all the nets and scrubbers in, we used to replace it every day/every other day. I don't think the tiny amount that's already been diluted that's left on the nets is enough to harm the fish. I'm not sure about using it as a fish friendly cleaner though, you may end up with too much of it ending up in your tank.
