I ordered from Hirocks, twice. The first order came in a couple of days ago, instead of ordering from their website, I took my chances with ebay. I was able to get the rocks for approx 1.00 to 1.65 per pound including shipping. The rock was beautiful and it was way more than 50 lbs. In fact, our estimation was that it was closer to 60 or 70. It was nicely shaped, needed some scrubbing, but you cant beat it for baserock. I put it into the 30 and 55 as it will be live eventually. The next batch I bought, has not come in yet, but it will get split between the sump and the seahorse tank. I am actually hoping the pieces are smaller this time so they will fit in the sump. that is how big they were.
