Should I do another change?

Recently one of my guppies was sick so I did a 50%-60% water change on the tank. The next day (today) he woke up dead so I took him out of the tank. The tank has like a white tint in the water I guess from him decomposing overnight but all the fish are okay. Should I do another water change on the tank even though I did one yesterday? I have ready-start bacteria so I don't think there should be a problem with the beneficial bacteria getting removed.
