Do you think I'm doing something wrong as my Nitrates are 0? How can I bring them back up and what should they be? I've added the Ammonia (full amount) tonight and will check back tomorrow. Maybe the Nitrate will be better then.......Oh I hope sodaizeUK said:Strange that your nitrates are showing yellow. They should definitely not be zero.
Yes, if ammonia and nitrite are both clear zero after 24 hours then water change and do a maintenance feed on Wednesday is a good idea. Otherwise continue giving a full dose as long as ammonia < 0.25 and nitrite <1ppm until they are both clear zero.
