They sure are. Well, if you want to maintain a healthy tank they are. Frequent, partial aquarium water changes help ward off disease and keep your chemical balance in check. Aquarium water changes are the perfect supplement to your filter to maintain the ideal water environment for your fish. The three questions that come up most often about water changes are how much, how often and just plain how?
How Much Water Should I Replace?
25% of your tank water should be changed at each interval after you get beyond the initial cycling period. This is the standard for most fish tanks. Larger fish tanks can tolerate a smaller percentage change of 10%-15%. This is because water changes happen slower in a larger tank.
How Often Should I Change My Fish Tank Water?
Aquarium water changes are recommended to be done once week no matter the tank size. If you are having chemistry problems, you may need to do water changes more often than this. Water changes are the best way to quickly reduce high chemical levels in your tank. Realizing that once a week might be a burden on some, it would be to your advantage do them once every two weeks at a bare minimum. Without this your tank can quickly get away from you.
How to Do Aquarium Water Changes
You’ll need a bucket, siphon hose, and siphon footer. One end of the hose goes in the bucket. The other end goes in the tank with the footer on it. You just drag the siphon over your gravel and plant leaves once you get it started. Vacuuming the plants is important because of the algae that can quickly build up. The gavel of course, racks up a bunch of debris. Gravel will start to make its up the tube, but don’t worry. The weight of it will bring it back down. This just leaves the debris, algae and water to get siphoned out.
Some Other Notes
Pretty simple isn’t it. Don’t forget to add conditioner to the water you add back to your tank. Also, you’ll want to get your water temperatures close to the same before adding it to your tank so you don’t shock your fish.
