Want to add more rock. Concequences??

[cvrle1]

Hey everyone.

I wanted to add about 20 more # of LR to my system. It has 35# now (it's 33 gallon)and all the parameters are as they whould be. Ammonia, nitrates, nitrites are at 0 ph is 8.4 salinity 1.023, calcium 440

Question is if I do add LR that is suposed to be cured (that's waht lfs said) what kind of an effect will that have on my whole aquarium? I do not want to go through another cycle because of fish and few corals that I have.

Someone help me out.

Marko

PS: I can't cure rock myself because I just don't have money to buy another skimmer right now for it.
