Bio-Cube 14: Best way to switch to Live rock

[kastawaykid]

My Bio-Cube has been up and running stock for around 3 months. Iwould like to know what is the best way to change from the Bio Balls to Live Rock, without upsetting anything in the tank or the cycle. Has anyone done this after their tank was established like mine? If so what did you do?
Thanks,
Kid

I did this, and I just slowly like 1/4 a day took out the balls. Then after that I put all the LR in back, but mine was cured already. If yours is not cured put it in slowly or buy cured.

Buy cured and swap them out. The live rock will have far more denitrifying bacteria than the bio-balls could ever hold therefore no loss in bio efficiency. Your system will thank you.
