I had absolutely no spike when I cycled my LR and LS in my 24G nano. Sometimes it DOES happen that there's no spike. We tested every day after the LR and LS were added and there was no spike at any time. Our test kits were/are fine. We did wait a full 6 weeks before we added any cleanup crew etc. So it IS possible that there will be no chemical change that is detected through our tests.

Even if you don't get any spikes or parameter changes wait a few more weeks then wait a couple more. How does one wait? Get yourself a good magnifying glass and look at everything. You will be amazed at what's going on in there!
