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.

actualy by def they are professionals

I would never cure the rock in my tank, unless it was a brand new tank set up then why not.. the rock I have cured I have done so in a seperat tank for only the rock.. when I did just waterchanges I actualy had two tanks, when I saw a spike, I would rince the rock and move it to the new water.. then back again for the next spike.. when I did the skimmer method I had the added bonus of being able to keep snails and hermits in with the rock to clean it up with out any die off of the clean up crue. doing this the other way would have resulted in massive death of snails and some hermits.

now having said that I have never been accused of under skimming either

at any rate, no store is going to do 100% water changes either.. to expensive. for one you got the water, the wages for the person doing it and the cost of the salt and wear and tear on the ro filters or DI canisters, electricity to heat the water, space for water while it is heating ect.. . Concider what a store will pay for a huge skimmer.. not near what they charge us and it is a write off as an operating cost. A relitivly new store in Vic has huge skimmers on there rock, they may do water changes also, but they seam to be providing the best enviorment they can.

As well when a store normaly gets rock in it is still pretty fresh and there is minimal die off so realy the load on the skimmer isn't that great. But I think more important would be the "no light" which I don't see anyone doing as they want to move the rock out as fast as they can.

I know store owners don't want to dedicate the Sq^ft to taking care of rock, but if they were going to dedicate it to any type of live stock that is the one to do it with.. as there is no losses so the amout of floor space is always good to make money.. now having said that I would definatly try to do a rack system to minimize the floor area.

one of the better stores for rock (well at least 8 years ago) had two 500 gal containers for rock.. never did a waterchange and was horably under skimmed, but the rock still came out nice. the problem is that LR is a filter in its self and will clear up a horable tank, but another problem arizes from this in that the more rock sucks up the more its pours become plugged up and the less it can filter.. so a store that just dumps rock in a tank and lets it sit till it is cured is decreasing the life span of the rock.. as far as for what I have seen for water changes the stores that do do them usaly do so after the rock had cleared the water so at that point they are doing nothing but waisting salt. what they need to do is conduct a water change as soon as they notice amonia in order to get the crap out of the water.


anyways we've beet this to death.. stores will do one or the other or a combanation of both.. some will light some won't, so decide what you want and find a store that does it that way

Salt is by no means cheap to any vendor. To ship salt (which is bought by the pallet) is very expensive.

The last IO order I got in on with a local vendor the salt came to roughly $32/bucket by the time it got to the doors. This was the sale price at the large vendor expo in vancouver. If your buying many more pallets at a time I can see it being cheaper but we just dont have that turn over. BTW this was shipped right from the factory.

As for the skimmer we have them on our LR tanks and your right the amount of stuff actually pulled by the skimmer is very little. We have a big Vertex on our rock tank but it is still pulling some protiens out.

Very well said. I couldnt agree more.
