Polyp Lab Colors product

Hey guys, just wondering if any of you have any experience with Polyp Lab's "Colors" product. On their website it says the product is designed for ultra low nutrient systems but it also helpsreverse bleaching by removing excess nutrients... I'm puzzled here because it is an amino acid complex that is designed to feed ultra low nutrient systems (in other words provide nutrients) but also removes nutrients? How?

Also I'm curious of your successes/failures with this product.
