(I asked this in my other thread, but I figured I might be better off starting a new thread for it.)
I have my two bettas in two 10 gallon tanks. (One betta in each 10 gallon tank.) the first tank and filter, I'd purchased in the beginning of July and started cycling the tank then. There were ammonia spikes and I'd change the water by 50%. I also noticed some slight nitrite spikes a few weeks ago, but they kinda went back down the last couple weeks and never went back up all that high any more.
Then all of a sudden, the other day, there was sudden a huge ammonia spike may have almost killed my betta. (I took it out and put it in a 1 gallon hospital container with epsom salt over night, and he became his old self again. It may have been the ammonia, or it may have been something else, I dunno.) I did 2 50% water within 24 hours, because the ammonia was very high, and then put him back in. (He's been doing fine ever since). Last night, his ammonia was slightly between 0 and 0.25, and tonight it's back down to a definite 0. The ammonia has never went *down* on it's own before.
The nitrites right now are a smidgen darker than 0 but not anywhere close to the next color, 0.25 on the chart. The same is with the nitrates, a smidgen darker than 0, but nowhere close to the next level on the chart, 5.0.
Will the nitrites start spiking next, or have they already spiked from previously in the month?
I understand the process now, (ammonia makes for nitrites which makes for nitrates) but it doesn't seem like my tank followed the pattern I expected. Unless there will be some huge nitrite spikes next.
