What will high pH do to my fish?
Harmful pH Levels
Tank or pond fish water with a high pH is highly basic or alkaline, and can chap or chemically burn a fish’s skin. Young fish are more sensitive to higher acidic water than adult fish. Fish water that has a pH of 5 is too acidic and will kill off fish eggs, they will not hatch.
What happens when the pH gets too high?
If the pH gets higher than 7.8, the water is becoming too alkaline. When water is too alkaline, it reduces the effectiveness of the chlorine — the pool chemical that kills pathogens. Water with a pH that’s too high also can cause skin rashes, cloudy water and scaling on pool equipment.
At what pH level will fish start to die?
The pH of your tank water has an impact on several aspects of water quality and water chemistry. For instance, if your pH drops below 6.0, the nitrification bacteria that keep your ammonia and nitrites (toxic compounds to fish) at zero ppm, will begin to die off.

What does pH shock look like in fish?
Symptoms of pH Shock
Some fish succumb to pH shock immediately. Others may exhibit symptoms including thrashing, darting, gasping, swimming near the water’s surface and trying to jump out of the tank. Such symptoms are the same as those that indicate toxins in the water — either cause is serious.
How much pH can fish tolerate?
The daily interplay of respiration and photosynthesis causes pH to cycle up and down during a 24-hour period. In most aquatic environments, daily photosynthesis is about equal to respiration and pH will usually remain within a range tolerated by most animals.
