To switch the aquarium from tap water to reverse osmosis water, you will first need to set up a reverse osmosis water filtration system. Once the system is installed and running, you can start by gradually mixing the reverse osmosis water with the tap water in the aquarium. Over time, you can increase the ratio of reverse osmosis water to tap water until the aquarium is fully transitioned to using only reverse osmosis water. It is important to monitor the water parameters during this transition period to ensure the health and well-being of the aquarium inhabitants. **
