## Description

API POND SIMPLY CLEAR Pond Water Clarifier provides a two-step approach for an incomparably clean and clear pond. API POND SIMPLY CLEAR Pond Water Clarifier quickly clears murky, cloudy pond water, and it breaks down pond sludge for maximum cleaning power. API POND SIMPLY CLEAR works by aggregating tiny suspended particles in pond water to form larger clusters which fall to the bottom of the pond where they are consumed by a super concentrated blend of beneficial bacteria. This solution is safe for fish and pond plants, as well as surrounding wildlife and pets, when used as directed. Exclusively for freshwater ponds, this solution is most effective when used every two weeks. 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: Great product - The water in my small pond was completely green. The old goldfish weren't happy. I wasn't sure anything would clear it up. Tried this product per the recommended amount. Didn't really noticed any improvement. Decided to double or even triple the recommended amount. The pond started clearing up within two days. Kept adding small amounts and now the pond is crystal clear. I can tell the old goldfish are happy again. This stuff worked wonders on my pond, but needed extra large dose to get it started.
Review: Safe and effective - It took a little over a week, but I now have really clear water in my fish tanks. I put a little less than a capful in a 10 gallon tank, and the water has been clear since. It’s natural, and with as little as I need it will last a very long time.

## Questions & Answers

**Q: how do i calculate how many gallons in my pond?**
A: There are online calculators you can find with google where you put in length, width and depth of the pond and it tells you.

**Q: Can this product be used at the same time as Api Algaefix?**
A: Yes I use the Algaefix, the Api Pond Simply Clear and the Pond enzyme all at the same time, regularly.

**Q: Can this be used at the same time as the api algae fix?**
A: I have a small pond and I use the algae fix first and wait a day and then do the Simply Clear the next day. You can do them together but I prefer to wait for the algae debris, which often happens. Simply Clear cleans it up.

**Q: Can this product be used in conjunction with api's pondzyme? if so, should applications be staggered in some way?**
A: Yes, you may use this product in conjunction with any other API product.  You do not need to stagger the dosages.
