Again my ammonia is 0.5 ppm. Nitirtes 0.25, nitrates 40ppm. Do i have to do a water change or not? How much nitrate canbe acceptable in cycling?
Thanks in advance reefers.

Now ammonia is 0.5ppm, nitrite 0.25 and nitrates are 40ppm. One more question how much nitrates are acceptable during cycling.

AM and Nitrites are un acceptable.

Nitrates can be as high as 80 ppm.

I Hang around 20 PPM myself... LPS corals need a little Nitrate.

No. No. No. You top off the tank with fresh water. Always. The water evaporates, the salt does not. You never top off with salt water...

Also, you have to have Ammonia and Nitrites at zero. Your tank is not cycled until both are zero, and you have nitrates.

Guys i got a nitrite spike about 2ppm. Ammonia is 0 so i added some ammonia to get the bacteria going. But the ph is dropping. It 7.5 now. One more thing some areas of my live rock is turning white. Can a water change helps or not? Kindly reply soon.

Adding ammonia won't help the nitrite, it could actually make it worse. The bacteria that consume the ammonia (nitrosomona) are completely different from the bacteria that consume the nitrite (nitrobacter). Adding more ammonia will be good for growing more of the first, but what you need to do is let the second one catch up.

At this point I'd do nothing. There is nothing larger than a pod alive in that tank right? So the nitrite isn't going to hurt anything while the nitrobacter population grows until it can keep up with the nitrosomona population. ...or atleast until it consumes the excess nitrite.

EDIT...had the names backwards..it's fixed now (it's too early) and FYI...the nitrosomona consume ammonia and produce nitrite..that's why adding more ammonia could create more nitrite.
