live rocks in sump ?

[georgiared 99]

I am in the process of taking down one of my 75 gal tanks and would like some opinions on putting the excess rocks in my older sump. The one that I am tearing down is over a year old and the other is almost 4 years old. I do not want to put a sand bottom in the sump. Would I have to have additional lighting for the sump, which would be almost impossible. Most of the rocks that I would like to put in sump are the old base rocks that were under the coralline covered rocks. I am not concerned with the growth on these base rocks, but was hoping that this might help with some filteration. Any ideas would be very much appreciated.
Thanks

From what I have read there is a lot of that that goes on. You would replace the bio balls with the LR from what I have read.

There is no problem using live rock in your sump as long as it is able to flow properly. I keep a few small pieces in mine and have found that the small fan worms reproduce constantly.

Go for it. I finally replaced the bio-bale in my sump with live rock a month ago. The rock serves three functions: 1) more filtering capacity, 2) a refugium for pods, and 3) catching air bubbles from my skimmer. The tank seems to be responding well. There has been a drop off in the amount of nuisence algae.

I keep lots of LR in my sump for the use of frags.
