Rock In The Sump

[Jewel]

I've always put all my rock in the display, is their any disadvatange to putting rock in the sump

I have rock in both my display and sump I have the light turn on on my sump when the lights turn off on my display it seems to help keep things more balanced I have a 90gal display and a 100gal sump I figure I have about 250 to 300lbs of rock

That's a ton of rock for a 90, I'm just looking at making my display More attractive with out a pile of rocks piles up in one another, I have 100 pounds in my 65, build thread to follow

I have minimal rock scaping in my display, so I have about half of my sump with live rock.
Have egg crate under it. Low flow. Covered in sponges etc.
Throw the odd hermit crab down there too.

 

[Jewel]

Thanks, is it necessary to light it

 

[Kyle1970]

I don’t believe so.
Mine gets light because I have chaeto down there too

 

[John721]

Most of the rock is in my sump I also have chaeto and micro algeas growing in my sump that's why I have the light turn on opposite to the display tank it's also full of cocapods and rotifers and other critters living in it

I also have rock, chaeto, calupra and mangroves in my sump.
I have lights on opposite to the display tank as this keeps the PH balanced as well.
