So I've had my 20g tank set up for about 7+ weeks now. During this time, I've certainly seen ammonia, which I have to constantly battle to keep below 0.25, but I still have no nitrites. Could it be that my bacteria aren't developing? Why? I've got 4 threadfin rainbows and 4 cory cats, along with a few danios and white clouds, in my tank. I do 25% water changes w/ a siphon every couple of days to try and keep the ammonia down. I have two filters, an in-tank whisper 10 and a hob penguin mini, so I've got 30 gallons of filtration. I'm not overfeeding--I feed a small amount every other day. pH is around 7.2, tempertaure is at 75. Right now, ammonia: 0.25 (time for another water change...sigh) nitrite: 0 nitrate: 0. I use Prime water conditioner, and API test kits--drops, not strips.
Why won't my tank cycle properly? I really don't want my fish to suffer from the ammonia.
