I've been cycling the tank using the household ammonia method, adding in enough to bump the ammonia to 3ppm every time it fell to 0 over the space of the last 5 weeks, as per the instructions here.
This has, obviously, led to all that ammonia ending up as nitrates, so whilst my ammonia and nitrate were testing at 0, my nitrate was still showing at 160+ (the highest my test goes to). So I did a massive water change, almost entirely drained the tank, and then topped it back up with new RO saltwater, and my nitrates are still at 160+.
Have I done something wrong here? My ammonia is showing at 0.25ppm, so doesn't that mean I'll need to add more soon to keep the cycle going and stop the ammonia converting bacteria from dying? Won't that just keep the nitrates sky high forever?
Sorry for all the questions, I feel a bit out of my depth here. :confused:
