does it work in salty water like in a port?

wouldn't this damage fish gills and fish slime ? i think it would..

I can see this as being a useful temporary clean up of toxins but algae thrive on Nitrogen and phosphate which aren't broken down by your technique. It's not removing the root problem of high levels of nutrients in the water. So this would need repeating regularly and may give the impression that pollution upstream can be ignored. Also not all microbes are harmful. Just think how important your gut microbes are

Really? Clean an entire lake. Give me a break! Even if you could get it clean, a week later rain run-off would pollute the lake soon.

These companies are so dodgy
