Hi I got 30lb of LR about a month ago and I'm curing it a big 50 gal container with 2 power heads. It looks like it went trough whole cycle first week big ammonia spike than ammonia at zero and a big spike of the nitrites. Now it reads 0 ammonia, 0 nitrite, and there are traces of nitrate. Is my LR ready to go in my main tank? if so how should I put it in is it OK to put in the whole 30 lb at once or go slow?
