My question was if a water change is better to do when the tank lights are off or on. So at 2 pm for instance or 2am when fish are sleeping and nightlife is active.20 percent water change is a lot imo

Certainly. But even if we disrupt things a bit, all that delicate life is actually quite resilient. Once a tank is teeming with life …Yeah I just wasn’t sure because tank life is so much more different when the lights go off…I think in some cases there’s more a activity when the lights are off…
