I had some beautifull rock in my old tank that I removed because I thought it could be the cause for a algae problem I had. I now think of putting the live rock in my new tank in a container that is connected to my sump with 2000l flow. The display will then aquascaped with the now unused rock. Will this be ok to do or do I have to put the unused rock in the extra container with the water flow from the sump to give the goggas time to move into this rock again? If that is the case how long before I can put them back in the display? The rock that I remove from the display will then go to the extra sump to help with filtration.
