Rock cooking, it does work.

Here's the process quote:

But before I do I just want to say that Bomber instructed me how to do it several months ago and it works great. So it is his process that I am trying to make popular and cause fellow hobbyists a lot less heartache in the long term.
The purpose of "cooking" your rocks is to have tha bacteria consume all (or as much) organic material and PO4 stored on, and in, the rock as possible.

The first step to this is commitment.
You have to be willing to remove your rock from the tank.
It doesn't have to be all at once, but I feel if you are going to do this do it all. In stages if that is easier but make sure that all of it gets done.

The new environment you are creating for your rock is to take it from an algal driven to a bacterial driven system.
In order to this, the rock needs to be in total darkness to retard and eventually kill the algae's on the rock and to give the bacteria time to do the job.

So basically you need tubs to hold the rock.

Equipment needed.
1. Dedication.
2. Tubs to cook rock in. And an equal amount of tubs to hold the rock during waterchanges.
3. A few powerheads.
4. Plenty of buckets.
5. A smug feeling of superiority that you are taking it to "the next level."

Here are the steps, if you have any questions I will try my best to answer them. What I don't know I am sure Bomber can/will instruct.

1. Get into your head and accept the fact you will be making lots of salt water if you aren't lucky enough to have access to filtered NSW.
2. Explain to significant other what is going on so they don't flip out. This process can take up to 2 months. Prepare them in advance so he/she can mark it on the calendar and that they won't nag about it until that date arrives.
3. Setup a tub(s) where the rock is to be cooked. Garages are great for this.
4. Make up enough water to fill tub(s) about halfway and around 5-7 buckets about 60% full.
5. Remove all the rock you want to cook at this stage. (The rock can be removed piece by piece until you are done.) I suggest shutting off the circulation beforehand to minimize dust storms.
6. Take the first piece of rock and dunk it, swish it, very, very well in the first bucket. Then do it again in the 2nd bucket, then the third.
7. Place rock in the tub.
8. Repeat steps 6 & 7 to every piece of rock you want to cook at this time. The reason I suggested 5-7 buckets of water will be evident quickly...as the water quickly turnsq brown.
9. Place powerhead(s) in the tub and plug in. Position at least one powerhead so that it agitates the surface of the water pretty well. This is to keep the water oxygenated. You can use an air pump for additional oxygenation if you wish.
9. Cover the tub. Remember, we want total darkness.
10. Empty out buckets, restart circulation on main tank.
11. Wait.
12. During the first couple of weeks it is recommended to do a swishing and dunking of the rocks twice a week.
What this entails is to make up enough water to fill up those buckets and the tub the rock is in.
First, lay out your empty tub(s) and fill buckets the same as before.
Then, uncover tub with the rock in it. Take a rock and swish it in the tub it's in to knock any easy to get off junk.
Then, swish it thru the 3 buckets again, and place in the empty tub..
Repeat for all your rocks.
Then empty the tub that all the rocks were cooking in, take it outside and rinse it out with a hose.
Place tub back where it was, fill with new saltwater, add rocks and powerheads, and cover.
Wait again unti the next water change.
You will be utterly amazed at how much sand, silt, detrius is at the bottom of the tub and every bucket. It is amazing.

How it works:


Some FAQ's.
When re-introducing the rock to my tank, a month or two from now, should I do that in parts to help minimize any cycling effect(s)...if there are any?
I never have. Really after a very short while, the ammonium cycle has been extablished. That's not what you're worry about though, it's the stored phosphates and that you have to wait it out.
When they are producing very little detritus - you'll know - then I would use them all at once.

Would running Carbon filtration and/or a PO4 reducing media help/hurry/hinder the process?
I wouldn't fool with it. You don't want the detritus to sit there long enough to rot, release water soluble P again. You want to take it out while it's still locked up in that bacterial detritus.




I hope this helps you out.
It really is a "miracle" and a low cost one at that.
The only monies spent are for salt and electricity for the powerheads which are nominal. Especially to rid yourself of Bryopsis.
Time and effort is all it akes. And really not that much effort.
I would say that 85% of my exposed rock had Bryopsis (hair algae) covering it.
There isn't a single visible strand on andy rocks in the tubs now.
Remember, the key is patience. Let this process run its course.

And a few last minute tidbits I remembered.
Your coralline will die back, receed etc.
My thoughts on this are GREAT!
Now my rock is more porous for additional pods, mysids, worms etc.
Coralline will grow back.
Throughout this process the sponges, and pods on my rock have not died off.
Everytime I do a waterchange they are there and plentiful.

If you have any questions please ask.
--------------------------------------------------------------------------------

Sorry I cant answer about the hydroids maybe someone else here has that experience.
 
We
1. admit we have a PO4 problem.
2. believe that a power greater than ourselves can restore us to salinity.
3. decide to turn our rocks over to that bacterial power.
4. searched reef central and found bomber and SeanT, made a copy of their process for easy access.
5. came back to reef central to say "I'm 2 weeks in and getting a lot of crud out."
6. mixed a LOT of salt
7. turned off the lights.
8. preformed multiple water quality checks.
9. corrected any parameters as well as could be.
10. swish, swish, swish.
11. sought through prayer and meditation for patience.
12. Having had a spiritual awakening as the result of these steps, we tried to carry this message to other addicts, and to practice these principles in all our affairs.

(Note: step 12 is real. This post is in no way meant to offend anyone that has suffered with the effects of alcoholism. Nor was it meant to diminish the 12 step program.)
 
Sean,

Would cooking rocks in a dark sump work?

Reason I ask is I have had about 40 lbs of rock in a sump for over a year, it does not shed any detrius (I clean the sump out once a month, I swish and dunk the rock and it stays really clean.

I have recently (a month ago) put them in their own dark container with a powerhead but they have not shed hardly any detrius at all, no algae on them or anything.
 
I do not believe you will get the effect you are looking for due to various reasons.
1. The available phosphates in the water column would prevent the bacteria from delving into the rock.
2. Detritus flowing through the sump would continually pollute the rock.
You will go forward but not very quickly.

Sean-

As I stated above my rock has been officially cooking for over a month now (getting close to 2 now that I think about it) and the rocks still are not producing hardly any detrius. I change the water once a week and setup 4 buckets of water and dunk, swish, shake/dunk, and then dunk/swish and don't get any debris/detrius coming off there.

Sound wierd?
 
I am in the process of cooking my LR, and planning my attack. Trying to minimize the looks I'm going to get from my wife. & buckets, 2 big tubs, the smell and the midnights mixing salt.

I have about 70lbs of LR with SPS and LPS on them. Thats not a problem because I'm going to frag them. Putting them on eggcrates with frag plugs.

My question is what do I do with my Polyp (Yellow) and My zooanthids that are on rocks that have HA on the LR and in between the polyps? What do you recommend for them. DO I need to make some hard decisions?

Also I have a 7" Maxima clam which I have had for 2 years and is attached to a piece of LR with HA on it. His shell also has HA on it???? What to do is the question?

Thanks
 
i would chip off a piece of the LR where the clam is attached too. Same for the Polyps and zoo's.

My clam had hair algae on the shell as well. Once I removed the LR the algae died on the clam about 2 weeks later,

You will go forward but not very quickly.

This I understand, my reasoning behind this question was simply it has been in a dark sump for right at a year, there was no detrius that would accumulate in that part of the sump, just in the 1st chamber where the skimmer pickup is. Once a month I would take the rock out, dunk and swish it then clean out any crap that may be in there. For the past 4-5 months there has been no detrius at all.

Now I have been cooking the rocks for well into a month and a half, officially cooking them to your guidelines that is and there is no detrius production at all, do you think they are cooked or should I leave them in there another 2 weeks or so?
 
Ok after reading DSB books for weeks my wife is looking at pictures on my desk top and says wow look at this tank I love it can we do this? She asks me. When I look at the picture its well the picture tells the whole story Ã" Ã¢â‚¬â„¢Ãƒ"šÃ‚º So now I am off to start a bb tank and my question is can I cook the rock in the tank as I pick it up today 1/7/2006 It will be a few weeks before everything is set up and running but if I leave the tank lights off and wrap it with black garbage bags will this be ok?

trueblackpercula,

the rock cooking process takes more then a few weeks, more or less a couple of months. you also want it in dark tubs, not trash bags since they have to be submerged.

you can cook it in your tank but you won't be able to have any livestock in there for a while and you'll be on detrius patrol every day siphoning up a fair amount of crud every day.
 
Elephen, I think he means to wrap the tank itself (not the rocks) in trash bags/dark material to block light from getting through the glass.

Trueblackpercula, I'd say it would work but you'd end up having more trouble getting a tank clean than a cheap tub when you're making the 100% water changes every 2 weeks and then once again when you're finally finished. With a cheap rubbermaid you can just turn it on a side/upside down and hose it out. Although, if you simply don't have the room for a cooking culture and won't be using the tank for ANYTHING else for 2-3 months, it would work if you covered the tank on all 6 sides.

It would work but I wouldn't want to go through the process in my tank. Thats alot of rock to be movng around and the potential for scratches is pretty good.
 
Trueblackpercula- can you be more precise on your plan to 'cook' the rock? I might of misunderstood you.
 
ok so if I go bare bottom do I have to cook my rocks? I got the tank today from glasscages and I will say I was very impressed with the craftmanship and how nice they were. Any case I have for filtration so fare is a MRC MR2 protein skimmer with a single injector and a blue line hd4o water pump. I just got in the mail a OM squirt for circulation with the same pump for circulation.
the rock cooking process takes more then a few weeks, more or less a couple of months. you also want it in dark tubs, not trash bags since they have to be submerged.
No I was going to cover the tank with garbage bags and filter the rocks in it. If it is going to take a month to cook than why can't I do it in the tank? I will have all the filtration in place and can secure the rock into place . I just think it makes more sense to me any way. Why should I have a tank up and running with nothing in it. Now for a second question if i cook the rock in the tank will after a couple of months will the tank be done cycling as well? Becuse if I have to cycle the tank and the rocks this is going to take a year before i get my first fish :)
P.S. I hope I am not high jacking the tread sorry

aslo were is a good place or tread to see some killer BB tanks.
 
You never <b>have</b> to **** rocks in any situation. It's just yet another thing some people are starting to live/swear by. And still others are completely against it . Those people that have called it foolish typical later admit they didn't read the instructions on the actual process.

Now, people are going to tell you to make 100% water changes even with filtration, a skimmer, etc on while cooking. I would think keeping the tank very clean (siphoning the gunk from the bottom regularly, as in daily), rinsing the filter, and skimming heavily would help the process. I'd also add a phosban reactor and replace the media twice during the 2 months. But I'd also remove the rocks for the weekly rough swishing in buckets. I just think by the end of it you'll wish you hadn't used the tank for this.

As for a cycle, you shouldn't have any at all. That's essentially what the cooking process does to the rocks. It makes them bacterial process plants with no photosynthetic critters competing for nutrients. I must have missed something in rock curing 101 because that question comes up way too much in this thread. No offense, I'm just kinda thinking out loud and curious why people think they'll need to cure their rocks again (by doing the exact same thing as cooking except adding a light to start growing coraline algae back) after cooking. Makes no sense to me.

But anyway, I know you have the idea of all this by your plan. Just remember what you're trying to accomplish and good luck removing and/or diluting your phosphates :).

Edit (Instead of a seperate post): What are the dimensions of that 120? Is it a true cube or a square? I'm just curious.
Thanks,
Will

No you don't HAVE to.
Bu I would seriously advise you doing so.
There are many people who went BB that didn't "cook" their rocks and will tell you horror stories about how their nitrates ballooned up.
As the rock is shedding detritus in such large amounts there is no sandbed to catch it.
"Cooking" your rocks in advance will save a lot of pain in the future.
THere really is no shortcut. :(
