Typically, in a 46-52lb average box 27" x 11" x 9" there is maybe 1 piece that is of medium/Large to Large Size averaging (8"-12") taking up about 1/3 the case, then maybe 2 pieces in the medium range (5"-8") taking up about the other 1/3 of a case and then the rest is mostly smaller  rubble to fist sized pieces. 

Note: If you want large pieces "only" you need to order "Fiji Show Rock" or "Kaelini Rock" which all are nearly 80% all between the sizes of 8"-24" each!

We are transhippers and "Do not hand pick" each individual piece for you.  As Tran Shippers, we are shipping about 2,000 cases a week, we inspect for good quality and dampness delivered from Fiji to LAX here in Los Angeles next to Walt Smiths facility, we throw in an additional gift in most our boxes (check your item advertisment to see if this applies) and then we ship all boxes immediatly out.   

When we are asked before shipping by the customer for specific sizes, we always do what we can to help in the way of for instance, if a customer says they want all large pieces, we would first highly advise the much larger Kaelini Rock but in the matter of Fiji, we would look for a box that might contain larger pieces and mark that one for that particular customer.  The same goes for any other size.  In any case, there are no promises or guarantees because there is absolutly no way for us to know ahead of time what we are getting shipped. 

The bottom line is you are not purchasing from a pet shop where you can cherry pick and that's why you are getting the rock at wholesale or near wholesale prices (or auction bid)!  Each box will vary in size and we always hope you'll really like what you recieved.  We always do our best to get you what you want but can't help it if a shipment of rock too large, too small or what ever comes in other than the quality which we are very particular with.

If you have an issue with the quality (not the size), we must be notified within 24 hours and per our terms of agreement and company policy, reserve the right to approve or not the replacement of your rock.  If we agree to replace your rock for you, it is your responsibility to ship 100% of it back to us, let us know if it's been exposed to anything such as commer or other medications or other outsider rock because if we resell it as base rock, we don't want to sell anything of bad quality to those customers any more than you would want bad quality rock.  Each box is weighed and marked in our database upon shipping so be sure to ship "ALL PIECES, EVEN ANY RUBBLE" back to us or there will be no exchange and your rock will be returned to you at your expense.  All Fiji or other Rock you purchased "Must be shipped back in their original box" or any guarantee or promise here is void.  Once we recieve the item, we will inspect it for the claimed flaws and if we agree that it is of unacceptable quality, we will send you another brand new freshly shipped case.  We limit our responsibility of reshipping back to you by only $20 credit which in most West Coast cases are free.  Anything above this for further shippings or special requests for additional heat or cold packs, or faster shipping methods would be the financial responsibility of the customer.

Just keep in mind that when buying bulk wholesale, you just like us are buying the entire box and what ever size comes in it.  It's like a big cracker jack surprise sometimes and 99% of the time most are extremely happy.  We always do what we can to please our customers so always attempt to call us at our expense at (800) 722-0421 and ask for me, Mike Baker the President of the company direct so I can help you on a personal level the best way I can.  Just keep in mind that selling to the public at wholesale, we don't make much more than $10 a case and just as much as a box may come to you small, medium or large, we too have no control over this and are forced to pay the full amount for Premium Fiji Live Rock too and we don't get any of these warranties are help discussed here.  I hope you are pleased with your case of live rock and will be a long time return customer.  We value your business and will always do what we can to help with in reason.  Thank you for your business!
