Agreed to disagree. Curing rock in the aquarium is somewhat different, you don't typically change more than 50% of the water at one time. If you cured your rock in a separate container (like many people do) you could simply change 100% of the water time and time again until you were satisfied. Your water volume would be small in comparison to the amount of rock you have or compared to your display tank volume. In such case I see little need for a skimmer and don't think it would be worth using. Curing rock in your display is different and could certainly benefit from a skimmer but this isn't the best way to cure rock.

and good skimming and dosing is very much a good way to reduce the amount of water changes required.. a water changed is to clean and replace, if you keep the water clean and replace elements you are acomplishing the exact same thing... In the 7 years I ran my big tank I started off with monthly waterchanges, then bi-monthly, then a few times a year, then to once a year.. no differance and everything thrived. now would I recomend this would out the use of a Ca reactor with good median and a good skimmer.. no.

I would argue a much smaller volume for that amount of rock. In addition you would need a skimmer rated for an equivalent of 1000 gallons to hand that much dead rock if not bigger. The cost of the skimmer, it's power consumption and maintenance would likely not pay for itself in a long time. Salt is fairly cheap to a vendor and could always use water changed from other systems for the live rock tank. Also no skimmer will replace water changes nor will it ever be as effective as removing nutrients and contaminants than the good old water change. I can guarantee you that any skimmer on a live rock tank will be more trouble than it's worth. Plus the skimmer seems to be the easy way out, using a skimmer and doing less water changes may be cheaper depending on how you look at it but certainly not better than changing all the water frequently. In terms of quality what is best? I would bet many vendors through little skimmers on there live rock tanks which are more decorative than anything, with the main purpose to impress customers.

That wasn't really referring to your post, just a general statement. However while on the subject if you agree a vendor can't possibly keep rock for long periods of time how could a skimmer possibly benefit such a system? Skimmers require time to remove nutrients while a simple 100% change removes them all in one go. Seems like a better solution in my mind. Skimmers simply aren't designed to remove large amounts of nutrients that quickly, they are steady state machines.
People at LFS are not professionals by any means in fact I don't know anyone who is a professional in that particular industry. How do you define professional?? Profit margins aren't large enough to employ such "professionals", you're stuck with minimum wage type employees who can bag a fish but certainly aren't experts. The only exception we get these days are the small chain stores which are run by the actual owner who tend to be very knowledgeable, however even with these stores it's only a matter of time before extra staff is brought in.
Of course we don't need the best of everything and that was certainly not my point. My point was that no store can be the best at everything and different stores will tend to focus more on certain things and not on others. This is why not all vendors will focus too much time and effort on live rock.
