I admire your rockscape, in particular the large stone on the left. Too often I see hardscapes consisting of tiny rocks that will be lost in flora. I myself wish I had used larger rocks in my tank.
It's weird how some people have success with DSM and others do not. I guess it all depends on the particular bunch of HC and whether it transitions correctly or simply turns to mush when exposed to emersed conditions.
