It's me again, I ordered about 100lbs of rock 50lbs dry and 50lbs live, the question is what has to be done before I put it in the tank? FYI I plan on starting up my 120 when I get the rock as of now it's empty. Thanx all.
Yes it is, I filled it yesterday to check for leaks and let the filter run for several hours to make sure all was OK then drained it before I ordered the rock.I believe the tank is empty
