What pH should my cold water fish tank be?

Will low pH kill fish?
Fish and other aquatic animal and plant life require the water they live in to be a certain pH level in order to be healthy. If the pH level is too low or too high, it can make fish sick, even kill them. A low pH means that the water is acidic; a high pH means that the water is alkaline.
How do I fix low pH in my fish tank?
A common method of raising the aquarium’s pH is by adding baking soda. 1 teaspoon of baking soda per 5 gallons is generally considered a safe amount for small incremental increases. It’s best to remove the fish from the tank prior to raising the pH.
What causes low pH in a fish tank?
Old Tank Syndrome in Fish. Old tank syndrome occurs in fish aquariums with high levels of ammonia and nitrite and low levels of water pH. It can be caused by overstocking, but is most commonly the result of inattentive tank maintenance.
How do I fix the pH in my aquarium?
Use reverse osmosis (RO) or deionized (DI) water to create the desired pH and buffering. Always prepare water and test pH before adding it to your aquarium. Use crushed coral or dolomite gravel for substrate. These calcium carbonate-based gravels slowly dissolve over time, raising and buffering pH.
Will 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 the pH is too high in a fish tank?
The aquarium itself will often reveal signs of high alkalinity as well. You may notice a sudden increase in green algae growth on the walls and ornaments in the tank. High pH levels encourage the growth of this algae and slime, which will thickly coat the plants and fixtures, making the water highly toxic for fish.
Does pH matter in a fish tank?

Will a water change lower pH?
Water Changes Dissolved minerals need to be cancelled out before you actually see a reduction in pH. And pure water is very close to neutral, with tap water ranging from neutral to slightly alkaline. Aquariums that simply get topped off with fresh water rather than water changes inevitably become alkaline over time.
