My 40 gal tank is cycling, ammonia spike has come and gone and I want to add LR. I've been told that it shouldn't be a problem as long as the nitrites aren't "too high". Any rule of thunb on "too high?" There are no fish in the system. I'm looking to add a 2-4 lbs (cured) at a time each week or so until I have all I want. I know I may get another spike but am willing to wait it out before adding fish. Any help would be, well... helpful. Thanks
