Aqua One pH Up Liquid
Aqua One pH Up Liquid provides a safe, controlled way to increase the pH level in your aquarium, helping you create the ideal environment for species that prefer more alkaline water. Because each step on the pH scale represents a tenfold change, even small adjustments can significantly alter water chemistry. Aqua One pH Up is formulated to allow slow, precise increases to prevent stressing your fish or disrupting beneficial bacteria.
Suitable for freshwater, tropical, and community aquariums, this treatment helps maintain stable water parameters for long-term aquatic health. Used as part of regular water quality management, Aqua One pH Up supports clearer, healthier, and more comfortable living conditions for your aquatic pets.

I’ve used this product for three months now and noticed a steady improvement in my community tank’s water stability. My fish seem more active and less stressed. The instructions are clear and the liquid mixes easily with water.

It works well for small pH increases. I added it once a month and kept my pH between 7.2 and 7.6. My tank has been stable without any fish showing signs of distress.

Great product for maintaining alkaline conditions. The liquid is easy to measure and mixes smoothly. I appreciate the slow adjustment feature, which prevents sudden changes to the water chemistry.
