I'm getting my tank ready for an oscar and I just ran into a problem that I haven't seen before. I'm using ammonia like I did before and as of the 11th day, I could add 7.5 mL of ammonia a day and get a 0 reading by the next day. Everything was going good and I got the nitrite spike around day 7. On day 15 the ammonia was at 1.0 so I didn't add any more. Day 16 (today) the ammonia is still at 1.0 and nitrite is still +5.0. I'm confused as to why the ammonia stopped going down. I leave the pump running 24/7 along with the bubbler under the gravel and the heater set at 81 degrees. Did the bacteria just die off?

So after the 11th day, you were adding ammonia everyday until day 15th when ammonia would no longer go down?

What filters do you have?

I added enough to get it to around 4.0 and left it until it started to go down. I added more everyday little by little to keep it around 4.0. By day 11 I could add 7.5 mL a day. Yes, on day 15 it stopped at 1.0. I'm using an Aqueon 75 pump with 2 of those slide in filters. I'd like to get a canister filter, but can't afford a decent one just yet. This is the way I cycled the last time and it worked just fine. This has me a little worried that something went wrong.

Problem with the ammonia reading on the chart is that it jumps from 4.0 to 8.0. Your ammonia could be closer to 5-6ppm. This will cause the fishless cycle to stall. Do a water change and bring the ammonia level down just above 2ppm but below 4ppm.

The ammonia was at 1.0 yesterday and as of an hour ago when I tested, it was still at 1.0. I only started at 4.0 from day 1. If the tank stalled, will it take long for it to start back up again? On day 14 I added about 3 gallons or so of dechlorinated water to raise the water level. I don't know how that would mess with the cycle though.

It's strange. The pH is only slightly yellow, like it would be 6.0, but the high range pH is 7.8.

Ignore the high range test, test again with the regular ph test again to be sure but im suspecting your cycle stalled due to a ph drop. If the test again shows a ph of 6 you need to get some baking soda and add a tablespoon per 20 gallons and retest in 30 minutes continue to do that till the pH is between 7-7.8

It tested 6.0 again. I added the baking soda and will test again in a half hour. Is the pH going to keep dropping like that?

The test kit only measure the pH up to 7.6 and it looks like it matches that color perfectly. I guess that means it could go over 7.6 with the same color. I only added 2 tbsp and the tank is 56 gallons.
