I put 50# of lr in my 55 gal tank to cycle it.The lfs told me not to scrub the rock because it would kill all of the living stuff. Against my better judgement I put the rock in without scrubing it. Now my nh levels are at 7.5 ppm and there is a ton of junk floating all over the tank. Do you think is will be ok. I am freaking out now.
