I'm with you. Dry rock is perfectly fine as long as it's purged of any built up phosphates just as live rock would need to be. The ability to "dry scape" and the reduction of any pests is a huge plus.

Most of the rock that went into my large tank was dry rock. Buying 90+ lbs of live rock wasn't in the cards @ $10-$12/LB. Honestly I'm disappointed with how slowly the coraline is growing on the dry rock and I do have sky high phosphates.
I think my problem with phosphates was due in part to using tap water for set up and over feeding. So I don't attribute it to the dry rock.

I had phosphate leaching for about 6 months. But honestly, a 4 lb container of GFO more than makes up for the savings in rock and the lack of hitch hiker crabs haha.
I went with marco rock so it wasn't as bad as some. From what I've seen with others, Pukani is your biggest offender. I think it's worth the risk though since Pukani is possibly the sexiest rock in the industry. Unfortunately … BRS couldn't ship it across the border … and there was nowhere to buy it when I set the tank up two years ago. I really wish I would have known about Eli selling pukani back then. Oh well, next tank I guess
