Cloverleaf Blanket Answer All Season – Year-Round Blanket Weed Warrior
Description:
Blanket weed doesn’t take a season off—and neither should your pond care routine. Meet the award-winning Cloverleaf Blanket Answer All Season, one of the UK’s most trusted blanket weed treatments, now supercharged to work in water temperatures as low as 2°C.
That’s a serious upgrade from the standard version, which taps out at 10°C. Cold pond? No problem.
Made from 100% natural ingredients, this powerful, fish-safe formula takes the fight directly to blanket weed (a.k.a. string algae)—those pesky hair-like strands that not only look awful but also steal dissolved oxygen from your pond water.
Left untreated, they create a low-oxygen zone that’s hostile to fish, plants, and anything else trying to thrive in your aquatic paradise.
Physical removal only clears the surface mess—Cloverleaf Blanket Answer targets the root of the problem by eliminating the microscopic spores that lead to repeat outbreaks.
Its unique blend of minerals and enzymes works gradually over five days, turning the water temporarily milky (don’t panic—that means it’s working), before restoring crystal-clear conditions and healthy oxygen levels.
Safe for fish, plants, UV units, pumps, skimmers, and filters, this is a no-fuss, high-impact solution you can use with confidence. It’s also repeatable throughout the year, making it a go-to treatment during any season, especially early spring or chilly autumn when algae still lurks.
