  1. Default Ammonia Dropping but 0 Nitrites

    It's now day 8 since I started dosing my 15Gl tank with pure ammonia. I managed to get the level of ammonia to about 3ppm and for the last couple of days the numbers have been dropping. Today I read the result as 0.5. I'm using the api liquid test kit and have double checked and asked other people's advice on the readings. The strips that I was using indicated that there was no nitrites present in my tank and I figured the strips were simply wrong, however today I tested for nitrites with an api liquid test kit and it told me the same thing. The nitrite reading for my tank is zero, but then why is the ammonia dropping? I'm very confused. My tank is relatively small and with the heater turned up so high (about 28C) it's causing a lot of condensation and the water level is quickly dropping, could that be the reason the levels are going down? Should I add some more ammonia or just wait and see what happens?

    Also today I added a moss ball from an established tank, I just hope it has some magic powers

    Do not add more ammonia - wait until it gets to 0 and then again more up to 2.0ppm - a tank your size doesn't need that much bacteria to grow - eventually, you will see nitrites and you can then add ammonia up to 1.0 to keep growing bacteria.

    Thanks for the quick response. I'm very confused though, shouldn't I already be seeing nitrites since the ammonia level is already going down?

    From what I've read on other posts, sometimes it can take 2 doses of ammonia before you'll see nitrites

    Maybe during conversion the same amount is not passed in next level, e.g. 4ppm of ammonia will you give you 2ppm of nitrite. ?? It's difficult to test when you have an established tank.

    I don't think the initial amount of ammonia determines how high nitrites will get - I know that sometimes someone will put in way more ammonia than needed (like 6ppm in a 10gal tank) and then they complain they aren't seeing the ammonia drop or nitrites show up at all.

    Kickstarting the cycle by spiking the initial ammonia appropriate to the tank size & adding it regularly will lead to a spike in nitrites at some point.
