Would recommend that you transfer your fish for now to the QT
and just change water every other day to keep water quality high. Use the shrimp method to cycle your main tank and test for and be sure you monitor ammonia and nitrites to start with. As the ammonia spike winds down, you should see the nitrite spike.
As the nitrite spike winds down, start testing for nitrates. This should start to increase. When ammonia and nitrites are 0, do the water change and then transfer your fish back. If you want to leave them in and take you chances, that of course is a risk you have to decide if you want to take. HTH
