Rock Rubble

[bubbymac]

I currently have a 29 gallon bio cube that has going for about 2 months now. i have been thinking about replacing the bio balls in the back of the system with rock rubble would that be wise or just keep what i have.

I know alot of folks that use LR rubble in theirs. I think it`s a good idea.

I switched my bioballs out after 4 months. It's a darn good idea. The more beneficial bacteria the better and less detritus!

What do you have in your tank corals, fish etc..?

 

[bubbymac]

fish w LR
will any live rock rubble work or does it need to be live. don't want it to screw up my system

 

[melosu58]

Already cured will be better. Less chance of dieoff causing a spike.

 

[DJLiquid]

Cured. I justed added cured to my existing live rock (removed some) with no problems.

thanks all no i will have to find some cured rubble

 

[buddha_red]

you could always use base rubble. no ammonia since its base rock

 

[bubbymac]

Or just take a piece of LR from your aquarium that you'd like to replace with a more attractive piece and break it down with a hammer.
