## Description

API POND ECOFIX SLUDGE DESTROYER Pond Water Clarifier reduces build-up of fish waste and consumes pond sludge, which is typically an accumulation of organic matter that degrades water quality and clogs pumps and filters. API ECOFIX SLUDGE DESTROYER contains all-natural, highly-concentrated bacteria to break down fish waste and dead algae, digest leaves and grass clippings, and reduce overall pond maintenance for the season. Use twice a week for two weeks as an initial dose at the start of the season, quick clean-up, and end of season, and once every two weeks for regular maintenance. With API POND products, it’s easy to keep a beautiful pond. For over 50 years, API has been creating innovative, research-driven solutions that make it easier to care for your pond. API POND Pond Treatment Supplies are designed to work in conjunction with each other to provide best results to control algae, promote healthy bacterial growth and help control and cure fish diseases and conditions such as ich and fin rot. They work to provide a safe, hospitable environment for fish such as koi, catfish, perch, goldfish and more. With API, you can spend more time admiring your fish, and less time scrubbing your pond. Make sure to use all products as directed in order to ensure the best results.

Review: A Fish Keeper's work is never done, but API Products help. - I have used almost all of the API products since we started keeping koi 4 years ago. I also tried several products by their competitor Microbe Lift and never got any positive results, except Microbe Lift Kh. All the API products can be used together, if you have multiple issues. You need to be sure you are treating your problem with the right product. That is why API has a product for every type of problem. We have expanded several times and now have an 8,000-gallon pond. We have a pump, filter, UV light, 2 bottom drains, a skimmer, and a sediment tank. I take water quality measurements every week, and occasionally issues will arise, even though we have a great system. That is why I still use Ecofix on a regular basis. The Ecofix bacteria keeps the Nitrates low and breaks down whatever plant matter is in the pond and pulled into the sediment tank. Then, I just skim out whatever is clumped in the sediment tank with a net. We do a back wash/small water change every month. We use API Stress Coat when we do water changes. Even though the bacteria in Ecofix breaks matter down and clumps stuff together for easy removal, the matter still needs to be removed. It’s not like it will completely disappear out of your pond, lol. Don’t we wish. You can remove what is left with a net and/or special vacuum to clean the bottom (never tried myself) and/or do a pump back wash to get the crap out of your filter. Using a vacuum is a drastic way to remove matter, and why I have never tried, because you will have to remove all your fish, or you will have a finding Nemo problem. Depending on where your Ph starts, I recommend putting in a little Kh/baking soda with the Ecofix. I use it with Ecofix to control the Ph. If I don't put in a little in when I use Ecofix, my Ph gets lower. I almost had a Ph crash before I figured this out. I only use a cup of baking soda for an 8000-gallon pond, so be careful. I found it works best for my pond, if I put in a little every other time when I add Ecofix. It’s best to put in less baking soda than you think you need and take daily measurements. That is how I arrived at 1 cup. API on desertcart sells test strips and liquid tests that I use to measure quality. (By now you might be thinking I have stock in the API company, and maybe I should. I only recommend their products because this is what I have found works over trial and error). No matter what product you are using, follow instructions for the correct dosage amount and where to put the product in your pond. Most people make mistakes in dosage because they don't know the volume of water in their pond. There are websites that help you calculate your pond volume that are easy to use. Many people don’t realize how the smallest increment of wrong dosage will impact the results and possibly their fish. Incorrect dosage is what I suspect when some reviewers say the API products did not work, or perhaps they weren’t using the right product for their problem. Like if you have an algae problem use Microbial Algae Clean, not Ecofix. The only product by API I don’t recommend is Algeafix. It didn’t work for the algae in my pond (before we got the bigger UV light for the new bigger pond). API Microbial Algae Clean (a bacteria) works better. A UV light works best. Hopefully, reading this review was helpful to you. Feel free to ask me questions.

## Questions & Answers

**Q: Trying to ship to Washington, amazon says it can not ship to this location.  Any ideas how to ship to Washington state?**
A: Send to a friend in a state that will accept order then gave your friend fed ex

**Q: What is the temperature range for these enzymes ?**
A: I don't really know the temperature range. We start using it around the last of March here in Tennessee along with zapl Algafix according to the directions. It stays perfectly clear during the winter months.The sludge comes to the top of the water for a while which you need to scoop off with a net. Then after that it will stay perfectly clear with if continue treatments according to the directions. I have had koi pounds for over 20 years and have tried many ways to keep the water clear and these two products are the best by far. Great stuff. Just be patient for a little while and you have a great pond. It also does not seem to bother my fish.

**Q: Can I use this product in my 20 gallon home aquarium?**
A: Yes, this product can be used in your aquarium or pond.

**Q: This looks like the same item as pond-zyme only in liquid form, is this a correct assessment? i use the powdered pond-zyme but thinking of trying this**
A: Same as powder but I like the liquid better because It mixes quickly into pond when applied close to your pumps. Pumps draw it in and then your water features dispenser it evenly through out your pond depending on how many water features you have. I have three but then again my pond is 45 feet long and 6-8 feet wide. Horseshoe shaped with a bridge to cross it.

Works great

### ⭐⭐⭐⭐ Pretty effective product

Not a miracle worker but definitely helps clear outside pond water and decrease the sludge. I think adding catfish would help more.
