My 5gal goldfish tank (for a 4 in goldfish) is currently at a really low pH (6.0-6.4). What is the ideal range for goldfish, what is the best way to alter the pH and how gradually does the change need to be.

Here is a helpful link: https://www.aqueon.com/information/care-sheets/goldfish Your local aquarium store will likely carry a powdered product to add to the water to increase the pH. The package will have dosing instructions. I hope this helps and please feel free to post any additional questions.
