If you’re new to owning an aquarium, it’s critical that you understand the proper way to change fish tank water. Do it the wrong way, and you might end up shocking the fish, or worse. As long as you do what you can to make them feel comfortable, they’ll provide you with a source of peacefulness for as long as they’re with you.
The Right Way to Change Fish Tank Water
First of all, at Seatech, we use only reverse osmosis deionized water in fish tanks, and we recommend that you do the same. RODI water is 100% pure H2O, which is one of the best ways to keep your livestock healthy for as long as possible. In fact, to help ensure that RODI water is available at your convenience, you can order it from Seatech H2O and have it delivered right to your home.
Once you have the best water, use the following tips to change fish tank water the right way.
● Changes must be made in small increments. New water should naturally blend into the existing environment. Seatech recommends only a 10% water change for the first few changes. Gradually increase it to 15% and then 20-25%.
● Change 15-20% of the water every two weeks for a reef aquarium.
● Change 20-25% of the water once a month for a fish-only or swim tank.
● Water can be removed from the tank by either siphoning or pumping it into a bucket or other container.
● Do not use water that is too hot or too cold. Due to the high temperatures in Phoenix, the water should be placed inside for at least one day prior to the water change.
● A temperature of about 78 degrees is ideal for many freshwater and saltwater fish. Specifically, the water in freshwater tanks should be 72 to 84 degrees, and saltwater tank temperatures should be 76 to 82 degrees. However, some fish require cooler water. Ask our aquarium maintenance technician for specific temperature recommendations for the types of fish you own.
● As you are changing the water in your aquarium, monitor the pH level of the water. About 5.5 to 7.5 is ideal for freshwater fish, and 8.0 or higher is recommended for saltwater fish.
● You should also keep your eye on nitrate levels. For freshwater aquariums, they are <80 ppm. For saltwater fish-only tank, the level should be <50 ppm, and for saltwater reef tanks, aim for <10 ppm.
