Fritz Wide Range pH Test Kit
Testing the pH of your aquarium water regularly to make proper adjustments is crucial to keep your fish, plants, and other aquarium animals healthy and stress-free. pH is the measure of acidity or basicity of liquids. Acidic water will measure between 0 and 7 pH, while basic, or alkaline, water will measure between 7 and 14. Knowing your animals is important: the preferred pH range of each species in your aquarium can vary.
A consistent pH reading is more ideal than frequent changes up or down. pH is influenced in the aquarium by many factors, including the KH content, respiration, organic waste decomposition, even the ammonia cycle. Because of this, frequent testing is recommended. Established systems should be tested once a month, and new systems or aquariums with fish illness require more frequent monitoring.

The test strips are easy to use and give clear color changes. I’ve been using them for three months and noticed a stable pH level in my planted tank. Great for beginners and experienced aquarists alike.
Neil Kerr –
Works well for checking pH changes after water changes. The color chart is simple to read and the strips stay fresh for a long time. Only downside is the test range is broad, so you need to interpret results carefully.
