I've seen that people tell you to change only 10% of the water but i don't understand what that means, i always changed all the water out of the tank which probably killed my last one. Dose it mean to take the surface water out and put more water in? And if it does when you add back that 10% of water do you add more water purifier? And after a month you change all of the water? Am i getting this right?
