Thanks for using Petco Pet Education Center, formerly Petcoach! You can probably extend it to one month if you are doing water changes that often. I would recommend you extend it to 3 weeks first. If that goes well then extend it to 4 weeks to see how it goes. You can then decide how long you can let it go before cleaning. Best of luck!
