Boy, if you’ve been plagued with String Algae or Blanket Weed you’re going to want to take a look at this. I was fighting it for about two years and it makes pond maintenance a real nightmare.
My weekly filter maintenance that took a minute or two became an every two day ordeal that took 10-15 minutes. Not much fun.
Fortunately, some of my Facebook friends from the UK posted about how they conquered the weed with Blanket Answer.
