Carefull with that ax, Eugene. You have had high nitrates for some time and while I agree with doing a significant water change, I don't recommend you do 50 to 60% all at one time. Water changes, due to temperature and salinity difference between old and new, are stressful to your ecosystem. You would be better off doing 10% water changes each day for 5 days. Less stressful that way.
