Nia Posted July 25, 2022 Share Posted July 25, 2022 To my knowledge, having some nitrates in your tank is good. I've been cycling my tank for almost 3 weeks and I tested my water 2 days ago and had 0ppm ammonia & nitrite, along with 5ppm nitrate. I just tested it and saw I have 0ppm nitrate. I don't have a fish in it yet, but I do have lots of live plants. Is this normal? Link to comment Share on other sites More sharing options...
Scapexghost Posted July 25, 2022 Share Posted July 25, 2022 Yes, plants consume nitrates. 1 Link to comment Share on other sites More sharing options...

Depends on how long you are going to wait before adding fish. If the bacteria goes too long without “food” you could throw off the cycle. just remember when adding fish - don’t add too big of a bio load or it could be too much for the bacteria to handle also and end up with an ammonia spike. Easier to grow into it. Link to comment Share on other sites More sharing options...
Cinnebuns Posted July 25, 2022 Share Posted July 25, 2022 Everyone here has given great advice. I just want to add a few things. Yes some nitrates are good and sometimes a heavily planted tank will get 0 nitrates. Keep this in mind if anyone tells you your tank is not cycled since you have 0 nitrates. That's not always true. It's just usually true because most people don't have enough plants to achieve this. As long as you saw ammonia and nitrites go up then down, you are cycled. Continue to dose ammonia until you add fish to feed the bacteria. Think of the bacteria as an inhabitant in your tank that also needs food. After you add fish, or even before, consider adding fertilizer to increase nitrates. Nitrate is one of the main nutrient sources for plants. I do not claim to be a plant expert by any means at all but i know its often suggested to try to keep nitrates around 20 ppm for plants. That said, I know many who have flourishing plants with 0. With plants it's all about balance and they typically have their balance down perfect. Link to comment Share on other sites More sharing options...

You tank is done cycling by the sounds of it. Add only a few fish at first and continue testing the water. Link to comment Share on other sites More sharing options...

Once your tank is "cycled" it is actually a continual process. its not a faster process - but depending on the amount of beneficial bacteria it will adjust the amount that it can cycle in the same period so thats why it seems "faster". Also, I agree with the others. If it was me - I would dose with some ammonia to both feed the bacteria - and test the cycle. Best of luck in the new fish next week!
