[guy cohen]

i use Brightwell Aquatics Microbacter7
and media in the samp
the qt is 220 liter
is that ok to put a fish o it?

Nope. You need to have zero Nitrite before adding g fish/inverts. Continue adding a bacterial culture and you will get there sooner than later

Nitrite is less harmful than ammonia in marine aquarium. But you still need to make sure it gets converted into nitrate.
I have used MB7 many times to cycle new tanks with great success. Maybe you can dose a little more MB7 and see if things get better.

MB7 is good I use it in all of my tanks.
