## Description

Safely and quickly lower the pH in your freshwater pond for more acidic water conditions with API POND pH DOWN Pond Water pH Reducing Solution. pH is the measure of acidic or alkaline water conditions. Water with a 7.0 pH level is considered neutral. Levels over 7.0 are considered alkaline, and levels under 7.0 are considered acidic. Different fish need different pH levels to stay healthy. Levels that are too high or too low can cause stress, illness and death, so pond water pH testing is crucial to the health of your fish. API POND pH DOWN Pond Water pH Reducing Solution is designed to lower pH in water that tests at an undesirable level. It is colorless and easy to use. It will not cloud or color water, and because it's phosphate- and nitrate-free, it will not encourage algae growth. Use as directed to keep pH levels in pond water between 6.8 and 8.0, an ideal range for garden ponds. 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: If you check your fish tank PH and need to fix it, try this product! - I use this in my 55 gallon freshwater tank after doing a water change and while monitoring water condition during the month. Takes a while and several doses to bring PH up to recommended levels, follow the instructions carefully and don't over-add at one time. Product works well if you follow the instructions and are patient. Add and then check tank water 24 hours later to allow to mix/stabilize.
Review: Great buy - Great buy and service! Thx.

## Questions & Answers

**Q: Can this be used to raise the ph of soil?**
A: No

**Q: Can this be used for indoor fish tanks, such as a 1 gallon fish bow to a 50 gallon fish tank?**
A: Can be used for water in all sized containers. I would recommend using either spring or bottled water for something as small as a one gallon (Beta and Goldfish sizes).

**Q: Hello can i use this in a 10 gallon tank, and if so how much do i use?**
A: Yes one 10ml capsize dose for that small tank, then test before using again

**Q: Hello so i did find out 1ml for every 10 gallons of water. So i m using under an 1/8th of a tsp can anyone confirm my math? Thank you**
A: One full cap is 10 ml (2 tsp) for 50 gallons,  half a cap is 5ml (1 tsp) for 25 gallons treatments. 1/2 tsp would be for 12 and 1/2 gallons of treatment Hope that helps.
