## Description

API POND-ZYME SLUDGE DESTROYER Pond Water Cleaner with Barley reduces build-up of fish waste and consumes pond sludge, which is typically a build-up of organic matter that degrades water quality and clogs pumps and filters. POND-ZYME SLUDGE DESTROYER uses natural bacteria and barley as active ingredients to break down algae and fish waste, digest leaves and grass clippings, and reduce overall pond maintenance for the season. This product is exclusively for use in ornamental ponds. Use as directed, dosing twice a week for two weeks at the beginning of the spring start-up season and at the end of the season, and dosing once every two weeks for regular maintenance. With API POND products, it’s easy to keep a beautiful pond. For almost 60 years API has developed premium solutions with proven and effective results for your family and ours. API offers a range of testing kits, water conditioners, and nutritionally superior food, because we’re dedicated to making a better underwater world. They work to provide a safe, hospitable environment for fish such as koi, catfish, perch, goldfish and more. At API, we understand the rewards and relaxation of fishkeeping because we have a passion for fish too.

Review: This worked great!! - I have a small 155 gallon pond. My two goldfish had babies and now the pond seems to be getting dirty sooner plus had an excess of algae. Within two days of the first use, the pond was clear! And my fish seemed completely unbothered. I have put it in a time or two since for maintenance and so far so good. Great product!!
Review: breaks down solids - As always, a little too expensive, but does the job very well. We have a small waterfall pond feature at our front entrance (no fish) but it takes maintenance like any other water pond. This product breaks down solids and somehow lightens the sludge after it breaks the solids. It even destroys leaves over time. Don't bother trying anything else, we have done that for you!

## Questions & Answers

**Q: how many gallons does this treat**
A: The container comes with a soup about  tablespoon sized and there is messing table on the container of how many scoops per 100 gallons. I have been using it once a week with 2 scoops and there's about 6 months worth in the container, by my guess. I hope this helps!

**Q: What are the ingredients? Does this contain peroxide?**
A: No peroxide

**Q: Hi my water is clear.  But will this work for cleaning up a sludge spot in my pond that is about 4X4? Or should I go with a pellet sludge remover?**
A: This product is excellent  I use it with either API pond flush or Microbelift PL. A super self discovered secret is mix 2 parts liquid bacteria above with one part pond zyme to make a cookie dough consistency. Roll it into a ball and drop or toss into pond directly into dirtiest sludge spots in the bottom of your pond. We use this technique in show ponds at a pond outfitter. Tried and true for over the last year. Unplug this UV’s for at least a day. You can substitute half barley extract if you’re having an issue with string algae.
I then supplement with whatever remaining liquid you need to add for the size of your pond.

**Q: I have a 600g pond. I dosed it last night. Water is still black. How long does this take to clear water?**
A: I was not a fan of this products performance. I've not had Black problems before, but lots of Green especially in Spring.  I think water changes and UV Sterilization unit was my clear water help!
