Review: Healthier water product - Have used this product all the time does seem to help in the Warmer months, to keep the pond water healthy Review: The product arrived labelled sludge remover but as we had ... - The product arrived labelled sludge remover but as we had had so much trouble even finding Pond zyme plus in Britain we decided to give it a go anyway. It has certainly made made a difference to the pond weed accumulating but I wish I knew whether this is the same stuff we used previously ie pond zyme plus. ## Features - Contains one (1) API POND-ZYME SLUDGE DESTROYER Pond Cleaner With Natural Pond Bacteria And Barley, 1-Pound Container - Contains natural active ingredients to break down fish waste and consume pond sludge - Breaks down dead algae and digests leaves and grass clippings - Helps to reduce overall pond maintenance and keep pond clean - Use twice a week for two weeks in ornamental ponds for start-up, end of season, then once every two weeks for regular maintenance ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B000OVCI2S | | Allergen Information | Apple Free | | Best Sellers Rank | 9,376 in Garden ( See Top 100 in Garden ) 71 in Water Garden & Pond Treatment 484 in Pools, Hot Tubs & Supplies | | Brand | API | | Brand Name | API | | Country Of Origin | USA | | Customer Reviews | 4.2 out of 5 stars 4,829 Reviews | | Global Trade Identification Number | 00317163021460 | | Included Components | Contains natural active ingredients to break down fish waste and consume pond sludge | | Item Form | Stick | | Item Type Name | Pond Sludge Remover | | Item Weight | 1 Pounds | | Item form | Stick | | Item weight | 1 Pounds | | Manufacturer | Mars Fishcare | | Manufacturer Part Number | 146B | | Model Number | 146B | | Number of Items | 1 | | Number of Packs | 1 | | Pet Type | Fish | | Target Species | Freshwater Pond Fish | | UPC | 885730609644 885479943481 317163421468 885509235029 317163021460 885232340557 885390880940 | | Unit Count | 1 count | | Unit count | 1 count | ## Product Details - **Brand:** API - **Item form:** Stick - **Item weight:** 454 g - **Number of Packs:** 1 - **Unit count:** 1 count ## Images ![API POND-ZYME - Image 1](https://m.media-amazon.com/images/I/81P3wccS3hL.jpg) ![API POND-ZYME - Image 2](https://m.media-amazon.com/images/I/91QVOW8ZmTL.jpg) ![API POND-ZYME - Image 3](https://m.media-amazon.com/images/I/A17vjkQ9+9L.jpg) ![API POND-ZYME - Image 4](https://m.media-amazon.com/images/I/A1DN2LBEZTL.jpg) ![API POND-ZYME - Image 5](https://m.media-amazon.com/images/I/710PtBqXxxL.jpg) ## Available Options This product comes in different **Size** options. ## 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! ## Customer Reviews ### ⭐⭐⭐⭐⭐ Healthier water product *by G***. on 17 March 2026* Have used this product all the time does seem to help in the Warmer months, to keep the pond water healthy ### ⭐⭐⭐⭐ The product arrived labelled sludge remover but as we had ... *by J***T on 2 September 2014* The product arrived labelled sludge remover but as we had had so much trouble even finding Pond zyme plus in Britain we decided to give it a go anyway. It has certainly made made a difference to the pond weed accumulating but I wish I knew whether this is the same stuff we used previously ie pond zyme plus. ### ⭐⭐⭐⭐⭐ Great product that works *by T***Y on 1 November 2025* I have a small outdoor pond with frogs living in there. The water was dirty and smelly. I tried a few natural things without chemicals but nothing worked until I used this. Now after a couple of weeks I can see the bottom of the pond and the smell has gone. ## Frequently Bought Together - API POND-ZYME SLUDGE DESTROYER Pond Cleaner With Natural Pond Bacteria And Barley, 1-Pound Container - API POND ALGAEFIX Algae Control 32-Ounce Bottle, FISHAQUARI (169G) - API POND ACCU-CLEAR Pond Water Clarifier 32-Ounce Bottle --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.pt/products/48702024-api-pond-zyme](https://www.desertcart.pt/products/48702024-api-pond-zyme) --- *Product available on Desertcart Portugal* *Store origin: PT* *Last updated: 2026-09-08*
