Rock cooking, it does work.

So you guys think the key to a successful reef depends on the phosphate levels?

Forget about good stuff, proper lighting, CA/Alk levels...etc. All things being in order if we try & limit the amount of phosphates everything will fall into place?

So at the heart of rock cooking lies the task of reducing phosphates?
 
So what happened to the phosphates removers? Do they not work? Rowaphos & phosban..etc.

Imagine a reef stacked with corals, you are actually asking someone to cook their rocks every 6mo-to a year? Is this really feasible? Why not & try to remove the phophates before they get trapped in your rock? Is rock cooking an after the fact solution only?

Most of my rock was base rock, or pretty much barren (brown) & yet after 8 months I am seeing signs of the rocks heading in the wrong direction. Not there yet, but eventually getting there I believe.

Is rock cooking a temporary solution? Requiring further cooking as the rocks are loaded? How long do you think the rocks can be used until needing to be recooked? I am sure this is a depends answer.

I am understanding more & still trying to convince myself. There is something inherent in all this that just repels acceptance (at least by me). Someone had mentioned something about the title "cooking," perhaps there is some truth to that?
 
1-Phosphate removers... will let boomber handle that one :)
2-Problem is that a good amount of the phosphate and crap in the rocks, came with the rock... even base rock..
3-Some people even cook there base rock... you would be surprised what comes out...
4-We try not to make the same mistake twice.. Good flow, limited feeding and a goodold turkey baster will keep loading to a min. So yes it depends..

My man,
It is to each his own.
Follow the path you feel most comfortable with Padi Wan.
Noone is going to kick you out of reefing if you don't cook your rock, heck, we aren't even going to look down on you for it.
But you constantly coming about and attemtpting to demean a very successful means of ridding organics...that is another story.

Do if you wish, do not if you wish.
Your choice.

Freedom of choice, yes we understand all that.
Again sorry for any demeaning that might have been done, I was trying to get at the heart of the answer. Although tough to accept I think by seeing the results first-hand it might make it easier.

Actually after reading the thread for the first time & before making any posts I concluded this. Our feedings provide the nutrients & trace elements for macro & any photosynthetic growth. Our lights provide the energy input which drives the photo life in our tank, which builds up over time. Overtime this energy input manifests itself & without any way of exporting this it will create further problems.

Your special grow in the dark bacteria are very special. Since they do not obtain their energies through light, but rather through the acquisition of other existing energies (such as our photosynthetic macros, or detritus). I was not thinking in terms of turgor or phosphates, & obviously could not mention this because it did not support my cause.

I am understanding how phosphates fit into this a little better now with all the help that was provided, but I still have some difficulties. Some of the questions that I have asked were simply brushed away, because they are not that easily explainable.

I really agree with #4
Sometimes you just get carried away or during your vacations your neighbor feeds too heavily. Over time (and possibly carelesness) your rock just collects garbage in the pores.
I have a new rule - A non reefer can not watch my tank when I go out of town. Keeping it clean goes a long way.
 
I thought I would post an update about my rock cooking. I've been cooking 'dead' rocks in my garage for the past 6 weeks in tubs. I seeded the dead rocks with a live rock from my display tank. I've been using Crystal Sea salt at a low salinity (1.017+) with RODI water. I've been a little lax on the 100% changes (going about every 2-3 weeks). My problem is that I've got some nuisance green algae growing on the rocks and when I swish the rocks not much is coming off (although when I get to the rocks from the display tank it spews the most). The garage is pitch black at almost all times except when I'm in there working on something and those blue tubs were closed tight for the past few weeks so I don't think light is the issue. The algae isn't everywhere either it is only on certain rocks and on certain surfaces. Any suggestions? Should I just step up the water changes? The water isn't heated and it has been chilly... the water is probably 60-65 degrees.

phrawd, your algae growth is probably caused by a couple of things. One being that you have used clear holding bins. This allows some light to enter the water and help feed the algae. I think one of the things that helps with cooking LR is that it is kept in the dark. At least that is what I have been lead to believe. I hope others will chime in with there experiences on this.
 
I don't think the clear bins matter. The rock in the clear bin on the left was in three blue bins the past several weeks with their lids closed up tight such that no light could enter. Plus the garage is dark all the time anyways.
 
What about using a wet/dry vac under water to remove some of the poop on the rock?? Not a substitution for cooking, just a supplement. Like after you are done "swishing" (we need better technical terms) it around, just hit it with the shop vac real quick.
 
If you're going to that I would take a turkey baster and squirt around them or a strong power head underwater. You can't suck nearly as hard as you can blow :)
 
Hey, do you guys think we can try carbon cooking? Cook the carbon to retrigger it for another round of use? Bacteria will turgor the hell out of particles & unwanted chemicals?

How would we know when we are done & if it were a success?
 
i need to go back and read more of this thread, but i just can't believe anybody would even consider doing this. in my tank the most interesting organisms are by far all the stuff that came with the LR. LR is a finite resource and the day will come when its harvest becomes outlawed. i think that we should all try to maintain the rock and all of the organisms on it, forever. so, for example, whenever tanks get shut down the LR should always go back to the LFS or to a friend............and i really question the wisdom of this "cooking" of LR.

i have a 50gal system with LR, LS and four small (but very active) fish. i don't use a skimmer or filter of any kind, but just keep the water moving. my nitrates always read at "0" (although i do have some hair algae problems). i hear about nitrate problems all the time and wonder how much of it can be associated with overstocking, overfeeding or other issues.

I'll be the first to jump on you for your post (I'm sure others will follow). First, LR is not a finite resource... no it is not infinite but it does replenish itself through calcium based coral skeletons. If you read Julian Sprung's book he talks about this particular myth in the hobby and has some very useful information.

Also, a lot of the pods, etc reproduce during the cooking process. It is the algae that dies off primarily.
 
yes, i'm sure they will. i play devil's advocate.

i think that it is a safe bet that we will see aquacultured live rock replace real wild live rock because that material (let's face it) does not build itself up within a time frame that would suit the people who collect and market. and there are going to be more policy responses to the same issue too.

i believe that Fiji actually had a temporary ban or almost-ban on LR collection a few years back. here is a sort of interesting short article on Fiji's LR trade

http://www.panda.org/about_wwf/what_we_do/marine/news/news.cfm?uNewsID=10626

and i just went back through pages 6 and 7 and see what i believe you all mean by "cooking"--apparently not throwing the rock into a pot of boiling water. there was some thread back somewhere in which that is in fact what was described.

...........but people really should try to conserve for the long term all of the LR that gets imported.
