API PH Down
pH levels are important when it comes to the health of your fish, and different fish need different levels of pH to be healthy. If your tank waters pH value rises above the ideal 7.0, it needs a fast-acting treatment to bring it back down to desirable levels. pH Up is such a treatment, making the water more alkaline and healthier. And because its phosphate- and nitrate-free, it will not encourage algae growth.
