Well I just added 14lbs of cured LR and another 20lbs of LS to my 29 gal tank. Will it go through another full cycle? Or just a little one? It was at the end of its ammonia cycle when all this was added.
what/where was your system at/like before the new addition? if already fairly well established, and the rock (new) in good shape-you may only get some extra output from your skimmer-if the tank setup was still relatively new, and the rock gets alot of die off,-you may get spikes detectable w/test kits.it all depends on that kind of stuff...
