How does using RO water in aquariums affect the pH and hardness levels?

Using RO (reverse osmosis) water in aquariums can have a significant impact on the pH and hardness levels.

RO water is essentially pure water as it has undergone a filtration process that removes almost all impurities, including minerals and ions. This means that RO water has a low mineral content and is naturally soft.

When RO water is added to an aquarium, it can cause a decrease in both pH and hardness. The lack of minerals and ions in the water can result in a lower pH, making the water more acidic. Additionally, the absence of minerals also contributes to a lower hardness level, leading to softer water.

It’s important to note that some fish species, particularly those originating from soft-water habitats such as South American cichlids or certain freshwater tropical fish, may benefit from the use of RO water. However, other species that naturally inhabit hard-water environments, such as African cichlids, may not tolerate the low pH and hardness levels associated with RO water.

To maintain appropriate pH and hardness levels in an aquarium with RO water, it’s essential to buffer and remineralize the water. This can be done by adding chemical additives or using specialized substrates and rocks that release minerals into the water gradually.

In summary, using RO water in aquariums can lower the pH and hardness levels. Therefore, it is crucial to monitor and adjust these parameters to ensure they are suitable for the specific fish species being kept.
