Depending on how high your chart goes, doing a water change with "off the charts' nitrite may even speed rather than slow your cycle. It will almost certainly make it clearly cycled sooner (if for no other reason than you don't have to wait for a ridiculously high nitrite level to drop... a "Cycled" tank only needs to deal with the nitrogen produced by the bioload on a daily basis... if your nitrite goes sky-high whiel waiting for your Bacteria Mark II to take hold, you'll end up cultivating more of the Mark II's than you really need to deal with the huge nitrite content of your tank, which will of course take longer than getting just to a "reasonable" level).ok im half way through my third week of my cycle with eight fish i have no ammonia but my nitrite is off the charts do i do water changes and slow my cycle or see if my fish withstand the cycle? please help and comment
The amount of salt recommended to me and posted here eliminates the toxic effect of the nitrite and is safe for fish (including cory), used it a couple times.ok thankyou just to make clear i would never torture 8 fish by dumping them in there i started with one and added one every five days for three weeks and will salt be bad for my cory i know thar they can be sensitive to salt
There is not much bacteria in the water.but is it worth possibly killing his fish?Try to do a 15 then come back in a hour and see. You could use water from an established tank. When I start a new tank I soak the media in one of my tanks. Then I drain the water I would pour down the drain for the water change into a bucket, and add that to the new tank. Then fill the other half of the new tank with fresh water.
I don't know if I would put 8 fish in a 55, never mind a 20
