The ASF SeaTest pH Test Kit will help you to monitor the pH in your aquarium. Since the pH value tells you if the water is alkaline or acidic—and most fish and nitrifying bacteria prefer alkaline environments—this is very important. Over time, biological processes can cause the pH of your water to drop below optimal levels. Protect tank and pond inhabitants who are very sensitive to pH changes and monitor it regularly with this kit. Listing and template services provided by inkFrog
