Our GH ranges between 15-19 dGH depending on the time of year How to test your water parameters It is also believed that hard water plays a role in livebearer immunity. Calcium ions present in hard water helps with bone and tissue development. Platy fish prefer slightly alkaline and moderately hard water. 10-20 dGH (178-356ppm) is the best general hardness for platy fish Other sources suggest that pH is less important as long as it falls within a fairly neutral range of 6.5-8.5 pH. Studies confirm that water on each extreme of the pH scale (4.0-6.5 pH and 9.0-11.0 pH) are dangerous and will stunt growth, prevent reproduction and cause death in fry.

Most experts agree that maintaining a stable pH is more important to platy health than achieving a specific pH value. Platy fish tend to do best in a pH range between 7.5-8.5 because alkaline water contains more dissolved minerals, such as calcium and magnesium. This most important thing is maintaining a constant temperature to reduce stress. Platies will tolerate temperatures outside of this range as well. They are native to Mexico, Guatemala and Honduras, where the average annual temperature is between 73-80☏ (23-27☌) in the coastal lowlands. Platy fish are tropical freshwater fish that require a tank temperature between 75-80☏ (24-27☌).
