adding LR for better bio filtration?

[roggy23]

i have an established FOWLR setup. i want to add LR and right now my fish are in my QT, they will be in there for 1 month is it safe to add LR without curing them?

well if you are positive that your fish will be in qt...and as long as you check for ammonia and nitrite before you add the rock
