Fishless Cycle help for 5G tank (used dr Tim’s ammonia)


Recommended Posts

Brando

Hey group,

I have a 5G tank that I am starting and I just added Dr Tims ammonia a day ago. day 2 just finished of the fishless cycle and my water parameters are: 

Ammonia: 4ppm
Nitrate: 10ppm
Nitrite: 1ppm

Am I on the right path? Does anyone have a guideline of the what the parameters should be each day of the cycle?

Any advice helps!

My understanding is that you start off High ammonia, low (or no) nitrite or nitrate, Then you should get increasing nitrite, still low (no) nitrate and falling ammonia. Then the nitrate rises and the nitrite drops. Once this 'cycle' has finished the tank is ready, when you have all zeros! There aren't any set figures you will see, this will vary tank to tank, it is just the trend (cycle) followed by the full set of zeros you are looking for to confirm it has happened.

After the cycle you may still get low NitrAte readings and as long as they are low that should be fine, one of my tanks has had that for nearly 10 years but the nitrIte and Ammonia must be zero and you need to have seen some previous readings of both of these to know the cycle has been happening.

The fact you have all 3 with a reading seems to indicate it has started but check daily the changes to the figures so you know where you are through the cycle! If you don't check frequently you may miss seeing part of the process and then you won't know whether it has cycled or not!

If you are setting up a very low PH tank for caridina the above probably won't work but for 'normal' tanks using tap water it is the way to go! Let us know if you are going the caridina route but I assume you are not as you have readings for all 3?

There isn't a set parameter for each day that you have to reach. But it has to reach 0ppm for Ammonia and Nitrite. And we should see Nitrate going up a bit to maybe around 20ppm before the tank is considered cycled. Measure Ammonia daily to see if it is dropping.

You can skip testing Nitrite and Nitrate daily if you want. Just test those again at the end of the cycle to confirm you see no Nitrite and some Nitrate.

Do I need to continue adding ammoni?

I imagine you need a constant source of ammonia otherwise the cycle would stall?

I haven't used the product you are, but what does it say/recommend on the bottle?

As long as your tests keep detecting ammonia, you are fine.

When it reaches 0ppm ammonia, that's when you need another source of ammonia to keep the beneficial bacteria alive. One type of bacteria in the tank uses ammonia as food and converts it to Nitrite as waste. Another type uses Nitrite as food, and converts it to Nitrate.

So when ammonia reaches 0ppm, that's the time to add fish or shrimp because your cycle is complete. If you are not ready to add livestock after the tank has cycled, you can add a small amount of fish food, or some organic matter that will degrade and rot. The rotting food will keep generating ammonia to feed the bacteria.

Some people like adding pure ammonia (not the stuff you buy in supermarkets for cleaning), like Dr Tims ammonia chloride. Adding fish food is probably easier. You mentioned you have Dr Tims ammonia, but did you also get any Dr Tim's bacteria additives like One and Only ?

 

When you are cycling a new tank, what you are doing is actually trying to create is a suitable environment for beneficial bacteria to grow. So don't forget to turn you temperature up to 26 - 27degC, and provide lots of oxygen and water flow. A food source (ammonia), oxygen and temperature are the key ingredients for a successful cycle. BB are living organism afterall, they need these basic ingredients to live.

I added dr Tim’s ammoni but I did not add any bacteria. Does that matter?

It depends....  are you patient enough to wait more than 4 weeks for beneficial bacteria to grow or not.

If you are impatient like me, you need to seed the new tank with bacteria. Either from a bottled product or from the filter of a mature tank.

      Really pleased to hear that your yellow shrimp tank is sorted now and you didn't even have to buy any new shrimps to repopulate, bonus! I hope the treatment of the CRS goes well, Ihaen't used any of those reatments so can't advise on those but would go with the info on the thread as that would be updated with the latest information/advice!  Simon

      I suspect the coral and egg shells have caused the GH to increase so I would just take those out and do a 50% slow water change! You will need to do water changes anyway whilst you're trying to re-cycle the tank, the treatments you used may have killed some of the beneficial bacteria, or it could just have been the chicken as you state? If the neocaridina were doing fine without the KH then it would be better to return to that set up, at least until you get it back to normal and stable. The important thing is not to make and big/sudden changes to the water parameters, the CRS will be more delicate than the neocaridina, but all shrimp are fragile creatures! Simon

      Great to hear that you are sorted! I wouldn't have thought Cordoras would eat copepods but as long as it is working stick with it? Simon

      Hi everyone. I've been keeping caridinas and neocaridinas in the same tank for about 2 months now. My neocaridinas were doing very well. Everyone was molting at their own pace and was breeding like crazy. Then I did a stupid thing of leaving raw chicken bits. While my shrimps ate the chicken, 2-3 of them died after that. And now my tank is totally haywire. I've tried doing water changes, tried vacuuming the substrate. My tank parameters are also REALLY REALLY bad.  Nitrates 40 Nitrite 1 Gh >7 Kh 0 PH 6.8 CL 0 CO2 <15 My ammonia is <0.02ppm My tank contents are aragonite sand, black active substrate(in a glass container), coral chips, coral stones, cholla wood, fissiden moss, duckweed, Indian almond leaf, java fern, a money plant, marimo moss ball.  What can I do to make the nitrates and nitrites go away? And is my kh and gh making any sense? I tried adding coral stone, egg shells to increase my kh but it's not working.

      Hi Simon, updates on the planaria and copepods. I tried using planaria trap and really screwed up the tank as I put raw chicken in the trap and when it wasn't trapping any planaria I took out the trap and left the chicken bits inside. I think they decomposed and caused a lot of ammonia as a few of my shrimps died(2-3). Then I used the benibachi planaria zero in the tank (did 2 water changes focusing on cleaning the substrate) and separated my snails and after two doses I don't see any more planarias. I also went to get 3 pygmy corydoras. That really made the copepods dissappear slowly but surely. Thank you so much for your help and advice!
