You need to get the ammonia down below 1, that is toxic level for your danios. Larger water changes will help.good job with the testing. Keep it up.

Cool! Wait at least several hours after water changes to test again in order to get an accurate reading. I usually wait until the next day. Keep us posted

The nitrite level is too high for your fish. Bump your water change up to 50%. It needs to be below 1.0 on the nitrites. Keep up the good work!

Ultimately, you want the ammonia and nitrite both to be 0. The time it takes for that to happen varies...could be a few more weeks, could be faster. In the meantime, you want to keep the levels of both ammonia and nitrite below 1 by performing partial water changes as necessary until your cycle is complete. Depending on who is speaking, nitrate should be kept below either 20 or 40. My understanding of the pH is that for most species, it is not necessary to alter the pH as the fish will adapt to your water.

Hi gilly, first let me say you are doing an awesome job. The hardest part is over, you are asking for info., and things are progressing nicely. One addition to the advice given so far, is that even when your ammonia and nitrite are 0, your tank is ALWAYS changing. For that reason you have to continue testing at least weekly. I do a 50% water change any time my nitrate gets above 10. The reason I do this is that although nitrates are not as "fatal" as ammonia or nitrite, they DO affect the health of your fish. Their natural immunities are lowered and they are susceptible to disease.
This is the # 1 reason to not over crowd your tank, it will be easier to keep the nitrates down. If your tank is planted with real plants they utilize some of the nitrate. The only other way to remove it is through water changes. Keep up the good work.

Your tank is cycled when the ammonia is 0, the nitrite is 0 and nitrates go up usually you will see 5 or above for them. The problem from there is that any new addition of fish, or disturbance of the nitrogen cycle bacteria (like cleaning your filters, or using medications), can cause a 'mini cycle' where the ammonia and nitrites go up again! This is why I said you have to continue testing, even with well established tanks. If it goes into a mini cycle, start your 50% water changes again until it settles back with 0 ammonia and nitrites.

I am presently cycling a 10 gallon with fish... I did this before I realized there is a better way. My next tank I would like to cycle with a cube of frozen fish instead of the live fish.. I think it would be easier since no fish means no water changes and a faster cycle.

Anyway this is from the last 4 weeks of the 10 gallon being tested / cycled with fish and a product called Cycle...

Week 1
PH 7.6
Ammonia .25
Nitrite .0
Nitrate 5.0

Week 2
PH 7.6
Ammonia .50
Nitrite .50
Nitrate 15

Week 3
PH 7.6
Ammonia .25
Nitrite 5.0
Nitrate 10

Week 4
PH 7.6
Ammonia .0
Nitrite .5
Nitrate 10

It still isn't finished but you get the idea of how the numbers can fluctuate. ;D Hope this helps some..

Your nitrites are critical!!! You should do a 50% water change. It is great your nitrates are coming up, the cycle is in progress, but 40 on nitrates are to high also, I always do a water change if nitrates get up as high as 20. My goal for fish health is to keep the nitrates 10 or below. Lots less stress on the fish.

I would continue doing 50% changes every day that the ammonia or nitrite get up over where they are today. Depending on how much you feed, or how many fish you have in the tank it might be every day. Look at tan.b 's profile and look at her posts. She was having the same problem, it took several weeks, but eventually her tank was fully cycled, and it is fine now. This is all a learning process for everyone. I am happy your levels came down with the change. Keep up the good work.
