Use this guide and a pH tester to achieve the best pH for your freshwater fish tank . The pH for freshwater shrimp is not listed on here but is recommended to be slightly acidic in the range of 6.3 – 7.2. By maintaining your aquarium at the best pH level, you will help your fish have a more efficient digestive and stronger immune system to combat disease. It is recommended you use a pH meter to test as it will be much more accurate than an aquarium test strip.

It’s also not a bad idea to research the desired pH of the plants you have in your tank, which will almost always correspond with the pH of the water in the plant’s native region. This is a reason why it’s a good idea to populate your tank with freshwater plants and fish native to the same region as each other.
Aquarium test strips are important to keep around but using a digital pH meter can give you a much more precise reading.If you are constantly having to monitor your pH, you may find value in checking out our 3 in 1 Aquarium Meter.
