My Fish Tank Won't Finish Cycling
Hey everyone, I have been cycling my 10 gallon planted tank WAY longer then I should have. It's now just starting to finish, but it won't. I have been adding ammonia for the past three days every time is drops to zero. I boost it up to somewhere between 2-4 ppm.

I'm following this - Fishless Cycling - Tropical Fish Forums - add and wait method.

I added ammonia at 8 pm last night and tested this morning at 8 to see if the ammonia was being processed within 12 hours. It's not. The strange part is that my nitrites are remaining at zero.

Any ideas why it's taking so long to finish?

I'm using the API liquid test kits for ammonia and nitrite. Current nitrite is 0. Current ammonia is about 2 ppm.

Mine took forever too (fishless). After 5 weeks, what helped me was a big old bottle of the super bacteria (may diff brand names) that my lfs had.

What would also help if you have a really good lfs with clean tanks and healty fish is a chunk of their filter medium. My lfs gave me a glob out of one of their filters. I added it to the back of my bio-wheel filter and within a few days, my tank was cycled.

Good luck.

use some of the filter media or a handful of gravel from your 29 gallon to help speed the process along............Just be patient till BOTH your nitrite and ammonia read zero.......Biggest mistake people make is thinking their cycle is done and add alot of fish all at once............add 2 or 3 then wait a week or 2 for the bacteria to catch up to the new bio-load, then repeat.............Good Luck!

Aww man! So no DPs yet?

Thanks for the help guys. When you say take some gravel from the 29 gallon, do I have to leave it in there after the tank finishes cycling or can I remove it then? Do i just put in on the other gravel or could i have it in a container of some sort?

Fishin Pole 08-20-2009 09:14 AM

this is what i would do with the gravel............get a cheap pair of pantyhose or womens kneehighs and put a fist full of gravel in it, place it in the back of your tank.............The gravel will contain some beneficial bacteria and help colonize the bacteria quicker, thus speeding up the cycle.............After a month or so, remove the sock and put the gravel back in your 29 gallon, or leave it go and you will always have a source for helping you cycle another tank..........I have a few of these in my tanks so i always have a bacteria source for an emergency cycle in case of needing a new tank setup.........

Alright thanks!

Seachem's "Stability" will also do the same thing with less fuss. And Nutrafin's "Cycle" has worked for me in the past, although that is not true bacteria but it operates the same. Stability is live bacteria and last month I used it to set up a 115g and a 90g tank and they cycled immediately [with 110 fish in the 115g and 85 in the 90g]. I know it works. I would never waste time with fishless cycling.

I agree 100% with you Byron. Never again. It was my first tank so didn't know any better.

The live bacteria also came in handy when I had to replace my filter after a big water change. Needles to say, I had an ammonia spike so I added the bac. and within two days, ammonia was back to 0.

I'm sure your local store would let you buy or just give you some water...dump it in...bacteria.
