Alright I kind of feel like an idiot asking this question but i want to do my best to make sure that all of my fish live so i just set up a 10 gallon in my dorm i'm using a filter media that's already been in a cycled tank as well as i filled 1/4 of the tank with cycled water i plan on doing at least a 25% water change each week. How long should i keep up the water changes until i can make it 2 weeks?
