twice a week actually... how do u know so much about me and my tank?
r u serious?
I have been on here for longer than you have, and have monitored/replied to some of your threads, and have done tons of research (how I got you on the nitrate part) in all aspects of the hobby (not just freshwater). Also, your setup is described in your signature.
Even if you do do twice weekly water changes wich are any less than 100%, there is no way you can have zero nitrate at any point in time in an estblished and decently stocked aquarium, and if you didn't have nitrate, you would most likely have amonia or nitrite.
