## Description

Keep your fish healthy and thriving by testing your aquarium water's pH regularly with easy-to-use API pH TEST STRIPS for freshwater and saltwater aquariums. Testing water parameters weekly helps prevent invisible water problems that can be harmful to fish. pH is the measure of acidity of water, on a scale ranging from 0 to 14. A pH of 0 is the most acidic, while a pH of 14 is the most alkaline. Different geographies have different tap water conditions with different pH levels, while fish require a specific pH level to thrive. A pH of 7.0 is ideal when keeping a community aquarium containing a variety of tropical fish. Goldfish and livebearers prefer a pH of 7.5. Many desertcartian fish, like angelfish and neon tetras, prefer a pH of 6.5 to 6.8. Mollies and swordtails thrive at pH 7.2 to 7.5. API pH TEST STRIPS for freshwater and saltwater aquariums test a wide range of pH levels from 6.0 to 9.0. Just dip a strip directly into your aquarium, and use the color-coded chart to determine if your water is safe or if adjustments are needed. Then follow the recommendations to treat the water – it's that simple! With API Aquarium products, it’s easy to keep a beautiful saltwater, freshwater or reef aquarium. For over 50 years, API has been creating innovative, research-driven solutions that make it easier to care for your fish and aquarium. API Aquarium 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 tropical community fish, cichlids, goldfish and more. With API, you can spend more time admiring your fish, and less time scrubbing your tank. Make sure to use all products as directed in order to ensure the best results.

| Directions | Just dip and read to measure aquarium pH in one easy step. In new aquariums, pH should be tested before fish are added. If necessary, adjust the pH with API pH UP, pH DOWN, or PROPER pH. In established aquariums, pH should be tested weekly since natural materials in the aquarium (such as fish waste and uneaten food) can cause pH changes.

### ⭐⭐⭐⭐⭐ Accurate pH tester for fish water
*by J***W on August 5, 2016*

Really happy I purchased these ... after learning via PetSmart that our tap water was super low pH due to a shallow well which apparently killed our betta fish after 7 days. I got these to test our water with conditioner (yes, I was too lazy to take another sample to the store and I'm pretty sure they use these same strips). I also wanted to test our bottled spring water, which is what I use for our new fish (no added conditioner on my part). I learned with these sticks that our tap water, with or without added conditioner, is very low pH and our jug of spring water is perfect. Our fish is still alive (and very active) so I'm thinking these testers are very accurate. I may never need 20 of these but for $6 I'm glad I have them ... if we move, get a saltwater tank etc. Overview-you take a strip, swirl it twice in the water, don't shake off and wait 30 seconds (I found waiting a bit longer was more accurate). The color is a little off if you look 5 minutes later so don't wait too long). Done. Easy and accurate.
