I would not add it all at once after 21 days of curing/cycling. It really takes months for the rock to rid itself of die off and get the bacteria up to full speed in my experinece. I would add about 10 lbs a week tops and watch nitrate and phosphate.
The rock works better in the tank. There are many who advocate using rubble in a wet and dry. I don't becasue this is a high oxygen environment and the rubble will act pretty much like the bioballs in terms of denitrification,in my opinion.
Depending on the porosity/density of the rock 3/4lb to 1.5 lbs per gallon should do nicely.
