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! ## 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.nz/products/1423401-api-pond-zyme](https://www.desertcart.nz/products/1423401-api-pond-zyme) --- *Product available on Desertcart New Zealand* *Store origin: NZ* *Last updated: 2026-09-12*
