agree with richierichdollar, a cycled tank should have nitrate reading, ammonia and nitrite should be 0.
of you already have nitrates , 0 ammonia and 0 nitrites
btw whats your filtration? and how many fish do you have in your 125 Gal?
the whitish stuff i think could be due to the fish shedding slime because of high ammonia.
