It’s really good

I’m an aquarium enthusiast and use other brand chemicals for my aquarium. I ended up with a koi pond later and have been using this ever since. I will say that this product has been amazing to use. Algae and muck are an afterthought. So in love with this product that I’ve been playing mental chess with myself to start using it in my aquarium. Highly recommend for your ponds!
