What would call a small boost in Nitrates?
Over stocking a tank?
Im just wondering cause iv had a very small amount of nitrates the last couple times i checked my water.
My tank has been set up almost a year and i havent added any new rock in months.
I do 5 gallon water changes every week in a 55 gallon tank.

Over stocking and over feeding are 2 things that can cause a rise in nitrates. How high are they after the "small boost"?
