    The process works well. I cooked about 20 kg's of seriously infected live rock. I cooked it for about 2 months and re introduced it to my system. The rock is thriving now and covered in corraline ;)

    Ok I did not see any mention on a skimmer there? I'm about to go this route with some rock as I'm not winning with the algae, I have some "new" rock that has been in my sump for a good few weeks and all the other rock will be cooked, so NO skimmer?

    Good point there SIMS, maybe the author left it out??? But from other articles I have read I'm sure I can recall them all mentioning heavy skimming.

    Quote.."Throughout this process the sponges, and pods on my rock have not died off.
    Everytime I do a waterchange they are there and plentiful. "....

    This statement is misleading
    I subscribe 200% to the philosophy of cooking....with the following additions...

    Firrstly..Many sponges (porifera) are mixotrophic. They feed not only on DOM and nano plankton but some that are found in our tanks also share a symbiotic relationship with cyanobactaria(photosynthetic). In short this means that they either need to filter feed from a higher than normal nutrient levels and or small amounts of light.

    This is not how we cook....we want sterile low nutrient levels and no light.

    Secondly... it is a well known fact that air is lethal to sponges... take them out the water... even briefly and they will most likely die.
    By the time our live rock reaches sunny South Africa, it has spent a good few hours out of the water. One rock that i have recently cooked was Kenyan... Sponge density on and within is amazing. I have witnessed fresh rock arriving; and then the decay....indicated by grey or white patches...as the decay worsens the rock literally oozes a translucent grey jelly.... which eventually leaves dark/blackish bruising which almost seems to stain the interior of the rock... This has led me to believe that many of these colonies actually survive within the rock.

    Skimming indicates massive dye off for at least a month. Sulphur dioxide reeking skimmate by the bucket full. Month two darkish brown...month three clear.

    imo.. Shake and blow clean with a power head...But i dont believe in scrubbing as Kenyan is so fragile that even after a light scrubbing it begins to crumble and disintegrate..... Heavy aeration and skimming to blow off ammonia...and as much circulation you can provide....The bigger the volume of water used the better...dilution...Carbon and phosphate removal 24/7

    Ok need some help with this thing - I have a bucket about 100l with an AM1000 and a Rio 4000l pump...

    Does temp make a difference to the cooking rock ie. do I need a heater?
    What should my SG be?

    Anything else I should watch out for?

    Thanks

    If you take all the LR out your tank to do this wont it have an adverse effect on your filtration and destabilise the tank? How do you manage to keep the water params stable with no LR in the tank for 2 months? I suppose what I am asking is how do you manage the tank the LR has come out of especially if the main reason is to kill off hair algae.?

    Good question Muz - for me I have a 300l display and a 200l sump - I am skimming quite a bit (skimmer rated 1500l) I have good circulation (x50+) and have 30kg's of rock in my sump - Plan is to cure this for a few weeks - no algae that I can see and then cure the rest once that is done so I will have 30kg's + in the systemall the time.

    Ahhh, so you are in the fortunate position to rotate your LR cos you have doubled up.. our systems are about the same. Funny ( not funny Ha ha ) but I only have hair algae on one rock, it is covered, not one square cm untouched, all the rocks next to it are fine. I dont have a lot of space in the sump cos my DSB is really deep so 30kg's wont fit..

    Interesting though.. I read an artical by Anthony Calfo and he mentions very heavy skimming during this process.

    Won't tangs solve the algae problem ??

    I have 2 lawnmower blennies, yellow tang and Regal tang no diffs.

    Muz take that rock out before it infects the rest of your system, even if you have to kill it get it OUT!

    Not to invent the wheel but if I ousted the rouge rock to the sump would that not at least 1) remove the algae from nearby rocks 2) the nutrients that are feeding the algae will be diverted to the algae in the sump..

    or.. remove him and scrub his naughty ass?

    If the rock has been in your tank awhile; then can the scrubbing. Just treat him like a mushroom, stick him in the dark and feed him.....well not quiet like a mushroom.

    I have frequently had this happen where one rock suddenly sprouts flowing locks... and it always seems to be when transferring rock from one tank to another...even tho the tank that the rock came from did not have a problem.
