Hello, I have a nano-cube 24dx and want to add some rubble to the second chamber and perhaps another 3-5lbs in the tank. It seems to me this would be a dangerous affair if I had fish and/or coral in it because it might cause a minor cycle. What's the best way to avoid this? I was thinking of using my 5 gallon quarantine to fully cure the rock. Is this the best way to go? Thanks!
