Personally i do a 30% water change twice a week in all my tanks or one every 5days 
. I do the 15 every week, occasionly leave it for 2 weeks but the filter gets fairly clogged up (the food I'm feeding has dried daphnia in, I manage to get the flake bits down but the filter sucks up some on the way down and the rest don't always eat the daphnia). The 20 I do every two weeks
) , sometimes every week but the nitrates are fine for quite a lot longer than 2 weeks.CFC said:I sorted the poll out for you.
Most of my tanks are once a week, two of them are twice a week.

Hey CFC, how much water are you going through with those huge tanks? I'm close to 300 gallons per week with all of mine
So, about the same as everyone else
