I have a 10 gallon tank that I set up at the beginning of July. It has one betta fish in it.
I was not clear on how high the ammonia was suppose to get, and at one point, it got to about 2.0 and my fish started acting weird. I saved the fish, did a big water change, and asked questions here and got corrected.
Now, i have started testing the water every day. I change the water when it gets to 0.25. Now I'm noticing that the ammonia is 0.25, maybe a little under, and the nitrites are 0.25. My nitrates are always 0.
Usually at this point ,I would do a water change. But when I do, it brings the ammonia and nitrite down to 0. HOw am I ever going to develope the bacteria that turns nitrites into nitrates if I always change the water when it gets 0.25?
Am I suppose to let it get a bit higher before changing it?
