i think he suggested losing the rocks as he assumed the tank was new and the rocks were a source of nitrates, i'm sure the idea was to move the rocks to a holding tank until the they were cured and the display tank was under control. Check the filter sock to see if it needs replaced, a polyfilter will also help remove unwanted waste. Also 15% water changes every other week would also help lower your nitrates and improve the water quality. I would definately invest in a good skimmer first, refugium later. There are also hang on back refugiums which don't require any drilling or anything like that.
