Increased nitrite in QT

Also if you're talking about nitrite then it's probally cycling, since you should only be reading nitrate with fish in the qt. I believe nitrite is not good for fish. You should run a hob filter to help speed the cycle.

Yeah I am currently running a AC30 with the carbon removed and just the foam and the bio ceramic type material. Had it running on my DT for a week prior to putting it on my QT. will go grab a new test kit and see what my reading comes back at. Until then, daily 1-5g changes

I wouldn't worry about nitrite or nitrate in a fish only QT. Nitrite/Nitrate are not toxic to marine fish unless the level is very high(>100ppm).
IMO you should monitor ammonia regularly in a QT. Get a good ammonia test kit and/or seachem ammonia badge.

+1 on the ammonia badge. I use two in my tank transfer method of QT

The Ammonia Alerts works really well, but don't rely on them for an actual reading. I've found the measurements they show are often 1/10th of the actual amount of ammonia in the water. Best practice is to dose an ammonia detoxifier as soon as you see ANY color change on the alert.

This is correct. Nitrite is not toxic in saltwater like it is in freshwater = even for (most) invertebrates.

You currently have enough bacteria that convert ammonia to nitrite, but the bacteria that convert nitrite to nitrate are not abundant enough. Just keep monitoring ammonia.

Here is a good article on nitrite in a reef:

As has been said, nitrite is not as toxic as in fresh. I am quarantining right now (first time for me) and have been watching ammonia real close. Nitrite and Nitrate are higher in my qt tank - seems to be going ok so far.
