So, it'll be one week tomorrow since I got my fishes. In my 5 gallon tank, I had planted it and cycled it fishlessly and it had been cycled for over a week before I got my fish (with me adding ammonia every day to keep the cycle going). The time after it finished growing the bacteria to turn nitrites into nitrates, the stem plants started doing their job and the nitrates were dropping, hitting 0 the day after I got the fish (and that day was a big rush of ammonia, because I had added ammonia not knowing if I would get fish, added Prime at the same time because I knew I was heading to the store, and accidentally added a bit to much ammonia, then the fish later in the day. Still showed 0 across the board the next day).
Well, because everything had been going so well, I pulled water to test yesterday but forgot to actually test it... I pulled water again this morning, and just tested them a few minutes ago. There was an ammonia spike! I was so stupid. :( As soon as the water started getting a greenish tint on one, I ran over and dosed Prime into the tank.
So, yesterday, the ammonia spiked to .5ppm. This morning it was .25ppm. Nitrites and nitrates were both at 0 for both days. What happened??? The tank was fully cycled, and there are a bunch of plants in there to absorb everything! :( That's it, daily testing, with actually testing it immediately after I pull water.
