Depletion of carbon dioxide can be what causes high pH in an aquarium. Adding tap water to your aquarium on a regular basis can also lead to higher pH levels. Untreated water from ground sources, including boreholes in your aquarium, can increase the pH level.

What causes pH to rise in aquariums?
Certain stones and rocks can raise your water's pH levels. Calcium-rich materials like limestone dissolve and mix into the water, thus increasing the pH. Also, consider adding shells or crushed stone to the bottom of your aquarium if you need to increase your pH levels.
Will low pH harm my 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.
What happens to fish if the pH is too high?
When the pH of freshwater becomes highly alkaline (e.g. 9.6), the effects on fish may include: death, damage to outer surfaces like gills, eyes, and skin and an inability to dispose of metabolic wastes. High pH may also increase the toxicity of other substances.
Aquarium Ph: Everything You Need To Know
What fish can survive high pH?
- Guppies. - Platies. - Mollies. - Swordtails. - Lake Malawi cichlids. - Lake Tanganyika cichlids. - Brackish fish.
What pH level is toxic to fish?
The acceptable range for fish culture is normally between pH 6.5 and 9.0. Fish will grow poorly and reproduction will be affected at consistently higher or lower pH levels. Very high and very low pH values, respectively, greater than 9.5 and less than 4.5, are unsuitable for most aquatic organisms.
How do I fix high pH in my aquarium?
- Use reverse osmosis (RO) or deionized (DI) water to create the desired pH and provide buffering. Always prepare water and test pH before adding it to your aquarium. - Decorate your aquarium with natural driftwood. ... - Add peat moss or peat pellets to your filter.

Will the fish survive in water with high pH?

What pH level kills fish?
In general, fish reproduction is affected at pH levels below 5.0 and many species (such as saltwater fish or sensitive freshwater fish like smallmouth bass) will leave the area ²¹. Fish begin to die when pH falls below 4.0 ¹².
