Hey guys I thought I would ask here, My wife is wanting new carpet next month in our den I will have to tear down my 150g and my 50g sump for this the concern im having is it has been up for 2 years and nice and stable. I know I can put about 1/2 the water in trash cans I have and put all the rocks in one and all the fish in another but should I replace the sand ? and also am I going to lose all my stability I have a lot of nice soft corals and a lot of fish and don't want to go through a cycle. plz give any advice you have
