Long story short, our (fishless) cycle in the 5g tank was coming along nicely. We accidentally let the nitrates get too high. There was about a week between 80+ and then 160+. didn't test nitrates in between. . Which clearly was a mistake.
We did two 50-60% water changes within 3 days.
Now we have ammonia (currently 2ppm, dosed it to about that last night) 0 nitrites and 80ish (at least) nitrates. Last night nitrates was around 20 after a 3.5g water change.
What may have happened? What should we do? Drain it all and refill?
