Will a high pH kill fish?
Very high (greater than 9.5) or very low (less than 4.5) pH values are unsuitable for most aquatic organisms. Young fish and immature stages of aquatic insects are extremely sensitive to pH levels below 5 and may die at these low pH values. High pH levels (9-14) can harm fish by denaturing cellular membranes.
What happens if your pH is too high in your body?
An increase in alkaline causes pH levels to rise. When the levels of acid in your blood are too high, it’s called acidosis. When your blood is too alkaline, it is called alkalosis. Respiratory acidosis and alkalosis are due to a problem with the lungs.
Can I use lemon juice to lower pH?
If you put 1⁄8 tsp (0.62 mL) of lemon juice in 1 US gal (3,800 mL) of water, you can lower the pH by about 1.5 points.

How do you balance pH in soil?
Two materials commonly used for lowering the soil pH are aluminum sulfate and sulfur. These can be found at a garden supply center. Aluminum sulfate will change the soil pH instantly because the aluminum produces the acidity as soon as it dissolves in the soil.
Will baking soda lower pH?
