API® pH UP pH adjuster raises pH levels in your aquarium to make water more alkaline when levels fall too low. pH is the measure of acidic or alkaline conditions in water, where a value of 7.0 corresponds to a neutral pH, 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, so it is important to test your water regularly to ensure pH levels fall where they should. pH UP pH adjuster is fast-acting, colourless, easy to use, and will not cloud aquarium water. Because it is phosphate-free and nitrate-free, pH UP pH adjuster will not encourage algae growth.
Determine the pH of aquarium water with an API pH Test Kit. To raise pH, add 2.5 ml. for every 95 litres of aquarium water. Take another pH reading before adding another dose of pH UP.
