Cycling question

This is a discussion on Cycling question within the Beginner Freshwater Aquarium forums, part of the Freshwater Fish and Aquariums category; --> If you have live plants already then it may not work for cycling as the plants will soak up the ammonia before it converts ...

Add the filter media and that will also help speed things along.

Patience is the key now you have "started" the cycle.

When cycling my new 26 gallons I decided to use some substrate from my well established 10 gallon. I just put it in a mesh bag at let it sink in a corner of the aquarium. There would have been about 2 cups of substrate in the bag. I decided to take ammonia and nitrite sample every day until the end of the cycle, and logged all of it. Here is my log :

According to my log, the aquarium was set up march 4. I did a fishy cycle (wouldn't do that now, anyway...) with 7 red eye tetra and first started to register ammonia 4 day later. It went up to 0.1ppm march 9, and that was the end of it, never seen ammonia since. Nitrite first appeared on march 10, too low to register my minimum test value (0.1 ppm) but still present. Nitrite went all the way up to 0,5 ppm by march 16, when I did a water change. Cycle was officially over march 21 with strong 0ppm for ammonia and nitrite.

The cycle took 17 days, about half as long as a typical cycle. There was no ammonia spike to speak of, but nitrite went quite high and stayed above 0,1ppm for 7 days. At the same time, the 10gal stayed right where it's normally at : 0/0/15-20ppm. My guess is that removing the filter, or a good part of the media from the filter might have had an adverse effect on nitrification in the 10gal.

When you did this did you have real plants?

Also were you using a water based test kit? What test kit did you use?

Just wondering. real interesting information. Thanks.

Edit: Also...how often did you do water changes?

If this is the result you got from removing filter media while cycling then there is no change... If it affected your tank then ammonia and nitrite would show up..Nitrate level is fine and would even be cut in half with a water change.

Substrate, filter media is perfect for using to cycling a tank, and as mentioned by the previous poster will cut down your cycle time. If you do not wish to purchase a mesh bag, a simple female stocking with a rubber band on it will suffice also. This is also a good way of keeping media "ready" to removed to start a cycle if one purchases another tank. It does not take much from an established tank to rapidly aid the cycling process.

If you do not have a liquid test kit but are using strips, then a highly reliable and often used one is the API Freshwater Master kit.

If you are using a liquid test kit at the moment, SHAKE Nitrate bottle #2 for a full 2 minutes before adding to the tube, this will give you a more accurate reading.

Both tank were unplanted at the time.

Test kit is a nutrafin liquid-based kit. Nitrate measurement of the 10g are approximate because I didn't have a liquid test for them, only strips. Would have been nice to see the progression, but I didn't do it...

Filter from the 10g was left in place, only substrate (gravel, about 3-5mm grain) was moved to the 26g.
Obviously in the 10g there where no change since I only removed a bit of substrate. Water changes continued as normal, 30% every week.

In the 26g, I changed 5,5 gallons of water (20%) on march 16, which helped bring nitrite down to 0,3ppm. Nutrafin aqua+plus water conditionner was used. No other water changes were performed for the duration of the cycle.

okay so Red Sea SUCKS. If its ever handed to you by an employee slap them in the face.

I waited 3 days and tested on the 4th day to be sure and it still read 0 so i picked up a API ammonia test kit and i finally got the correct results which showed about 4-5 ppm. I add 1 ML ammonia daily my question is, do I add 1ml daily and wait until it starts dropping? Do I stop adding ammonia when it drops or lower the dosage? i put in a driftwood from my cycled 20 gallon to help speed it up and tomorrow I will get some stockings and put some gravel in there. The 10 gallon is heated to 85 degrees.

Well you want to keep adding a small amount of ammonia but you don't want to make it too much (don't let it go above 5ppm). As soon as you see the Nitrite come, do one last addition of ammonia and then stop.

Once you test 0ppm for ammonia and nitrite

test your nitrate. when you see the nitrates and 0ppm of ammonia and nitrite...

then do a water change :)
