The one-star rating is purely to highlight the product's potential danger to ponds:
As a caution I would like to point out that the label on the bottle warns that the product is toxic and highly dangerous to fish and all aquatic life, and may have long-term effects. I have politely asked Amazon to amend their sales page to include a warning to this effect. I have three ponds and have therefore had to return my product; the return has been handled by Amazon with their unfailing courtesy and enormous efficiency.
