I did a test on my tank earlier today before the co2 came on and it was fine, 0 nitrite, but now when the pressurised co2 is on- 0.25 nitrite
please advise

please advise
If your cycling your tank then (as Dan the man states) just wait for the filter to process the nitrite to nitrate.AdAndrews said:what do you advise? shall i just sit tight and one day it will be 0 nitrite?
My filter is off for longer than that when I clean itAdAndrews said:the filter was off for all of 30mins if that,

bacteria die off at a rate of approximately 9-10% per day, and the population would be back up to size within a few daysDan Crawford said:How long was the filter off for when you rescaped? If it's over a few hours then most of your bacteria would have died of and you need to repopulate it.
Adding some ammonia in a brand new tank would speed things up a bit but they will almost always cycle since there is always some ammonia in tap water, there is bacteria on the gravel and decor, new or old and dying plants will excrete ammonia too.
