I only do 20 to 30% water changes once a week. You should test your water regularly to see what the Amonia, Nitrite, and Nitrate levels are so that you know if your changing enough water.
you should do a 50% water change every other week

It's recommended to perform a partial water change of about 25% every 2-4 weeks in a 29-gallon fish tank. Additionally, you should clean the filter once a month and regularly remove any debris or waste from the tank to maintain water quality and a healthy environment for your fish.
1 gallon tanks & smaller need to be changed/cleaned every 5 days.
you should change it every week so it will always be clean.
Extremely required information: size of tank! 1 gallon = every 3 days 5 gallon = every 5-7 days 10 gallon = probably a week or two. It does depend on your fish. What you should do, is test the ammonia every day. When ammonia shows up, mark how long it took, and that is how many days the tank can go without a complete change of water. Cycled tanks are a different matter. They only need occasional partial changes.
