Can I have too much LR?

Before everyone gets jealouse, this is only a six gallon nono reef.
I converted my sons eclipse 6 into a nano reef and was wonderind if 18lbs is to much. I want it covered side to side and only leaving about 4" empty to the top. Will this work?

Some problems you might encounter are:
1) Displacing so much water that the system will no longer hold anywhere close to 6 gallons and cause it to become more unstable.
2) It will probably limit you to less mobile creatures.
...but it will look really nice w/ some mushrooms in there, a few inverts...

If the rocks fit openly you will be okay, but just packed in there I would worry about circulation and trapping and decaying of detritus. As long as you have good water movement and open areas I see no harm. Make sure you think about the actual water volume when stocking. Good luck... nanos are neat

Just make sure your fish can swim around.

No fish just corals.
