When I first got the tank, I felt like I was constantly testing the water, and making a lot of changes but that's what's nice about getting an established tank. The only things I do now is clean the glass every 1-2 days which takes less than 5 min.. Once a week, I take the filters out and clean them in the sink which takes about 5 min. I'll add some I/O water whenever I see the level go down and that's about it.
