Nitrite issue

[Betta-Chetta]

So my biocube has been running great for 10 months. I recently set up a frag tank and it was saying it was fully cycled. So i moved all my corals to the frag tank and noticed my corals werent as happy as before. I tested my aquarium and it showed very high nitrites. So i moved all the corals back to the biocube and now its show nitrites at .25ppm. Why would this be? I havent done a water change on it in three weeks. I also run nitrate/ nitrite reducing pads in my tank. Any body has any ideas that would be great!!

Were you feeding the corals?

 

[Betta-Chetta]

I feed my corals with reef roids once a week. I do reef fuel twice a week and i add calcium and alkalinity twice aweek as well.

What method did you use to cycle the frag tank?

 

[Betta-Chetta]

I used bio spare and a damsel to help cycle the tank

 

[VietExtender]

How many corals did you place into there? Since its newly cycled, you could’ve added too many and the bioload couldn’t handle it.

 

[Betta-Chetta]

I had put 6 in there

Let the tank cycle a bit more and check on ammonia and nitrites again. Then add two corals first and see how that goes.

Sounds good! I also put already cycled media in there as well to help

Yep. Good advice from VietExtender. Tank just needs to cycle a bit more and build up more nitrite eating/converting bacteria. Be mindful that that will increase nitrates so more water changes will be in your future. Gotta keep those coral happy ;)

Will do!
