How to raise pH in your aquarium

If you are new to aquariums, you should know that there are many vitals to take care of with an aquarium. Simply buying an aquarium and giving food to the fish is not going to be enough. You need to make sure that the aquarium has clean water that is also suitable for the fish. To have suitable water, you might want to check the pH level of the water. It is essential to have an optimum pH for which you might want to raise it in some situations. There are several ways through which you can do this. We have listed down a few of those methods for you to try.

Aerating the water

Aerating water means that carbon dioxide level is reduced in the aquarium, which then results in a rise of pH level. Adding an air pump to the tank will help in aeration, and is an excellent method to receive desirable results. However, you will have to make sure that the large currents produced due to the air pump are not disliked by the fish. 

Change water of the aquarium

Very often, the polluted water causes a fall in pH level. To avoid this, you should consider removing 20 percent of the water every 2-3 weeks and replacing it with taped water. By changing 20 percent of water, you make life easier for yourself. It is best if you do it in small amounts rather than attempting to do it entirely at once.

Adding baking soda

You can find baking soda in your kitchen quite easily, and it can serve different purposes. Adding it in an aquarium raises pH and reach the optimum level required by the fish. However, you would want to add it regularly to maintain the pH level or else it would drop. Do not add too much baking soda in one g because it can harm the fish.

Change your substrate

Another way of raising pH can be by changing the substrate. Similar to how adding tannins can reduce the pH, adding crushed coral or certain shells can increase the pH. You can even add these materials inside your filter to hide them in case you are interested in that. In addition to this, you should pay closer attention to the amount of substrate you are adding as they can easily exceed your expectations of a higher pH. 

Boil Driftwood

While simple Driftwood is used to reduce the pH, boiled Driftwood can be used to raise the pH of the aquarium.  Some people do not want to remove Driftwood from their tanks, but its presence reduces pH, which is harmful to some fish. In this scenario, it is best if you boil it.


The list mentioned above has received many positive reviews throughout several years. You can rely on it to provide you with suitable information in regards to raising the pH of the aquarium. If you are unsure about your decision, you should add baking soda to the aquarium. It is an easy and effective method to carry out the process.
