## Description

Product description Ornamental water gardens and ponds are enclosed ecosystems, sometimes factors like fish load, uneaten fish food, organics such as leaves, sludge and unwanted debris may disrupt the balance. Leaves, grass clippings, algae, uneaten fish food, fish waste, and decaying plants all contribute to build-up of sludge which is not only unsightly, but unhealthy, as it consumes oxygen. Directions Apply once to treat muck and sludge in ponds and other water features. Suitable for various pond sizes and types. Treated water can be used immediately after application. For best results, use with other Pondworx products.

Review: 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!
