You said you had neglected your tank, how did you arrived at 0 Nitrate and 0 Phosphate? Maybe you stripped your tank nutrient so fast.

what i mean by neglect is, i havent had as much time as i once had, im not testing things as much and im not changing the filter socks every three days, i left them in for weeks....
anyways i did a water change and i added carbon...fingers crossed
