I have a betta fish named Wilfred in a 5 gallon hex tank with a filter... Now I know I need to change the filter cartridge every 2 weeks and that I need to do a 15-20% water change every week... but how often do I need to take everything out and scrub it and change the water 100%?How often should I clean my betta fish's tank?Never. Performing 100% water changes removes all the beneficial bacteria that lives in your substrate and filter media. The bacteria breaks down fish waste.
Stick with your weekly 25% partial water changes.How often should I clean my betta fish's tank?You shouldn't change the water 100% unless there is a very bad disease because it gets rid of important bacteria. You can scrub everything down when it gets covered in enough algae.How often should I clean my betta fish's tank?you shouldnt have to change the water 100% since you have a filter. It might be a good idea to get a small aquarium vacuum and vacuum the rocks out once a month or so. That way you can clean up what the filter cant get. Replace that with bottled water. If you decide to use tap water, make sure you get a chemical at the pet store that takes out the junk that is in tap water.How often should I clean my betta fish's tank?never do a 100 % water change just do 25%How often should I clean my betta fish's tank?WOW! You sound like you are doing everything right. I have betta fish (Scarlet) in a small glass bowl, he is a male betta and has plenty of room to swim. I clean Scarlet's tank once every month and that is all it takes! I use a toothbrush (old of course) to clean the sides of the tank. Keep the tank away from the window or direct light. It causes algae. Make sure you are using declorinating drops before putting Wilfred back in his tank! Hope this helps. I change his water completely every time. Scrub everything clean whenever you change the water. :)
