Not at all. I'm pro live rock as well but all live rock I have purchased have always had some sort of pests that I then have to eradicate. I just prefer to lower the risk.
What I'm trying to say is that dry rock in an established system is not always best because it has no way to manage excess nutrients which explains why pest algae is more susceptible. Had the dry rock been cured and matured outside the system then introduced once matured we would have better luck not having pest algae because it now has beneficial bacteria to help as a biofiltration.
In my case I had the time to allow dry rock to establish itself and I was in no rush to add livestock. I used live rock and sand to seed but it takes a long time which most are not willing to wait.
Both types have their benefits but need to be employed appropriately
