The survival of fish in your aquarium depends on several factors including the pH of the water in the aquarium. The water pH has to be maintained at a certain range for the fish to thrive. The fish can’t survive in water with low pH. Natural changes such as decaying organic matter or unconsumed fish food can occur in your tank which may drastically lower the pH of the water. Therefore, it is your duty to regularly check the pH level and make sure that it is maintained at levels suitable for the growth of the fish. Below are some of the best ways you could use to raise the pH of your aquarium water without affecting the fish.
Change the water regularly
If you fail to change the water of your aquarium, the pH is going to drop. One of the effective ways of maintaining the pH is through regular water changes. You don’t need a complete water change. Monitor the aquarium and if you notice that the aquarium has a fluctuating pH then do a 40-50% water change. While changing the water, be sure to get rid of all the waste, and uneaten food from the aquarium since it also helps in stabilizing the water pH of your aquarium.
Use Crushed corals
This is one of the most effective natural ways of raising the pH of your aquarium. Coral shells and skeletons have a high concentration of calcium carbonate and related compounds. Calcium carbonate is alkaline and can increase the pH of the water without posing any danger to your fish. You can achieve this through two different ways; place a couple of bags containing crushed corals in the aquarium or add smoothly crushed corals in your filter so that the water becomes enriched when it is filtered. The amazing thing about corals is that they are readily available and they won’t cost you a lot of money.
Increase the aeration in the water tank
Aeration simply means that you are increasing the oxygen concentration in the aquarium water hence lowering the concentration of carbon dioxide. A lower concentration of carbon dioxide translates to a higher pH. You can easily achieve this by increasing the aeration in the tank.
Just like crushed corals, limestone contains high levels of calcium carbonate which is ideal for raising the pH of your aquarium water. It doesn’t matter whether the water in your aquarium is saltwater or freshwater, limestone will serve you well. Limestone is largely used in landscaping hence you can easily find it in construction stores. It is cheap and one of the most efficient ways of increasing and stabilizing the pH of aquarium water. The Texas Holy Rock is one of the most popular limestone that is used to maintain the water pH while serving as a fantastic decoration as well. Be sure to use the limestone sparingly because you don’t want to over-rise the pH and most importantly, you don’t want to overcrowd your tank. Try to put one or two medium-sized limestone in your tank and observe the changes in the pH of the water.
Add baking soda
Baking soda is another easy and natural way of raising the pH levels of your aquarium water. Be careful with the amount of baking soda that you add to your water. If you add an excessive amount of baking soda to your tank, you risk spiking the pH levels which may result in the death of the fish. Another mistake that you need to avoid while using baking soda is adding it once, and then you forget about it. It won’t help. You are required to a moderate amount of baking soda to your tank constantly for better results.
Use Macro algae
One of the benefits of growing macro algae in your aquarium is that it helps in keeping the water pH stable. The macro algae achieve this by absorbing harmful carbon dioxide. The macro algae provide stiff competition to the other “toxic” algae in your water tank. The algae also produce dissolved oxygen which circulates throughout the water in the tank hence providing the much-needed aeration of the water. This is one of the best and cheapest ways of maintaining stable pH for people who are just starting out in setting up their home aquarium. It is simple and less tedious compared to growing corals. The algae can survive at any temperatures and are capable of handling any changes in the environment.
