Nite out 2 keeps the nitrates and ites
you should avoid putting chemicals in your tank at all cost. the stuff that adds elements is ok but if you have to put anything in your tank to get rid of anything you are not doing something right. The bilogical filter should not need to be maintained after the tank has cycled. Save your money.
A good water change schedule with RO
is all you need.
