fishless cycle taking forever!

After nearly 3 weeks of ridiculously high nitrite levels and no increase in nitrate, i decided to do a huge water change to get the nitrite to a readable level. I'm now dosing the ammonia a bit lower for a few days and will do another water change if those levels get crazy again. Hopefully things will get moving again now, i have no idea where all this patience is coming from, i guess i'm just determined to do it right and not give up!

Don't be surprised if the nitrites sky rocket again, part of the process. same thing happened to me. I stopped dosing amm to 4 and cut it down til I got a amm reading of 2-3, within a week my tank was done cycling!

Fishless Cycle

Good morning Amy..

If you're anxious to get some plants and fish into your tank, you can go ahead with the plants. Next large water change you do to get the toxin levels down to a safe level, get some plants into the tank. Plants will like the more acidic water.

Get some Java fern, Anubias and some mosses. You can also go with some fast growers like Pennywort and Hornwort, Anacharis, and varieties of Hygrophila. Let those do some of the work of filtering your tank water for a couple of days.

Then, get a few real hardy fish. Some that will have no trouble getting through the cycling process, like Feeder Guppies, Platys and some Zebra Danios.

Keep testing the water and when the toxins get too high, bring them down to a safe level with a large water change.

Could this mean a large water change every day or every other day to get the nitrite down? The ammonia has been dropping from 5 to 0 in 24 hours for well over a month, should be pretty close now

Thanks for the advice on the plants, i've been thinking about plants recently. As for the fish, i think i'll wait untill the tank's completely cycled, thank you

Cut your amm down, dosing to five is high, most people dose to 4, if the nitrites are unreadable ( to high)do a large water change and dose amm to only 2-3. What are the nitrates reading? Sounds like you are almost done with your fishless cycle!!

Please do not add fish right now, no need to!

Hi Amy! You are almost there!! I encountered the same problem and it took 9 days for my tank to cycle once i started doing massive water changes to get my nitrites under control. Yes, i know it defeats the purpose of fishless cycling & no water changes, but its what worked for me. I believe (i cant back this up with facts, just experience) that the insane nitrite levels somehow inhibit the nitrtie>nitrate conversion. Once the nitrite levels are under control(keep dosing amm), things seem to move along quite quickly!

No nitrates yet just did the huge water change last night to get nitrite down to about 2ppm i also dosed ammo to about 2ppm. DW no intention of getting fish untill i'm fully cycled, i've waited a long time as it is so a few more weeks won't matter

It certainly seems like high nitrite levels stall the cycle, fingers crossed things should get moving now. It was your post that made me do a large water change to get levels down so thanks
