I have a 55 with approximately 55 pounds of live rock hat has been up and running for over 1.5 years. I ordered 10 pounds of cured live rock rubble for the fuge i'm finally able to get up and running. I would think I still need to put the rubble in a bucket with a powerhead and monitor to make sure there is no mini cycle. Is this correct or would that small of an amount not cause a big problem. Any feedback would be appreciated.
