Id never buy any chemical to remove algae. Algae is due to an imbalace of light and nutrients, tomm barr says the two largest causes of algae are ammonia and co2 either too much not enough or inconsistent amounts. If this liquid kills algae it either removes nutrients from water or does something to block nutrient absorption which would also be bad for plants, instead of buyong a product to get rid of algae how about stop putting the things in a tank that cause algae. This algae fix liquid is like buying a pill to counteract the side effects of a pill one is taking to correct a self inflicted maladie, just cyclical thinking that keeps one in an endless cycle of spending money on aquarium products. Decrease light or increase depending on nutrient intake, decrease feeding, do consistent water changes to remove excess nutrients and replace electrolytes, and yes nerites and amano shrimp will eat hair algae and can manage it.
