I'm not sure what you expect out of this product. The website sells a single product, ie, a bag of white powder that is described as -
So it's essentially dried up and crushed ... plants??? What do you do with it, pour it into your filter? How is that any different than crushing up dried grass clippings, pulverizing it into a powder and throwing it into your skimmer?
If you look at the "science" justification they link to on it's website, it's an EPA Fact Sheet on bioremediation, or "phytotechnology". The link, which is not even to the official US EPA website, describes the use of constructed wetlands as a method of remediating various super-fund sites. So how is that related at all or in any way to residential swimming pools??
I think if you look at it more carefully, you can see how this is nothing more than a merchant website using a fancy webpage and some random links to sell unwitting customers what amounts to a bag of magic beans. I did an internet domain name search to see who the domain name is registered to and it is a company in FL. I searched the FL Better Business Bureau and the company is not accredited by the FL BBB but has an A- rating with one unresolved customer complaint. So, one has to ask, do you trust buying a product from a company that is not accredited by a state BBB and has an unresolved customer complaint??
If you are truly having algae problems, then I would suggest you review the TFPC method of pool care and ask specific questions about your pool. It would also help us to help you if you post your own test results and describe the algae problems you are seeing and why you are using polyquat-60.
