API® pH UP pH adjuster raises pH in your aquarium to make water more alkaline when levels are too low. pH is the measure of acidic or alkaline conditions in water, where a value of 7.0 is neutral pH, pH values above 7.0 are considered alkaline, and pH values below 7.0 are considered acidic. Different fish need different pH levels to thrive, so it’s important to test your water regularly to ensure that pH levels fall where they should. pH UP pH adjuster is fast-acting, colorless, easy to use, and will not cloud aquarium water. Because it is phosphate- and nitrate-free, pH UP pH adjuster will not encourage algae growth.
