API pH Down
API pH Down pH adjuster lowers pH to make freshwater aquariums more acidic for fish and plants when levels rise too high. pH is the measure of acidic or alkaline conditions in water. A value of 7.0 corresponds to a neutral pH. A pH values about 7.0 are considered alkaline, and pH values below 7.0 are considered acidic. Different fish need different pH levels to be healthy. It is important to test your water regularly to ensure pH levels fall where they should. API pH Down pH adjuster is fast-acting, colorless, easy to use, and will not cloud aquarium water. Because it is phosphate-free and nitrate-free, this pH adjuster will not encourage algae growth.

Plant safe product to lower ph in my shrimp tank that kept rising. I only need a couple of drops and the Ph has stabilized. The product is going to last forever.
