Why Do We Cure The Way We Do?

traditional curing goes something like this, toss the rock in the tank with little or no light and no inverts or fish and let it go for two weeks, maybe add a skimmer after two weeks then lights after four and critters after six. Now, I'm relatively sure I will never undersand the skimmer thing, unless its to avoid damaging the skimmer itself with all the crud in the water, but what I want to examine is the no light policy.

Personally I think that it would be a good idea to light it up 24/7 durring the curing process, while curing the two biggest problems are DOC's and nitrogen containing Ions. both of which are consumed by algeas such as bubble algea and black hair alge as well as more desirable forms like macroalgeas and coralines. Now if you ran the lights on your newly curing Live rock for 24 hours a day then the various forms of algea might just be able to keep up with the Nitrogen containing Ions pouring off of the rotting dead stuff, and if that were to happen then the living components like brittle stars and bristle worms wouldnt be under such a strain, wich could lead to fewer deaths and a shorter curing period. Also if we could keep down the nitrogen containing ions then couldnt we have a cleanup crew that could maybe eat some of the dead matter off of the live rock before it decayed. Now, Nitrate is the least offensive of the threenitroen containing compounds, especially in marine pH's so naturaly we wuld strive for converters such as bioballs, ceramic rings, biomedia, biowheels and biospira, we would still need to do water changes, buit with a normal cycle thats imporant too, however we wouldnt be taking out as much nitrogen we would be converting it to algea in our tanks, wich we then convewrt into larger cleanup crew critters, if we did this we would need a very overstocked cleanup crew, perhaps 3 snails or hermits per lb of live rock. Give the idea some thought please, I eagerly await your replies
 
Hi Opcn...my only input/hypothesis on this is that we're not only looking at nitrates here but also at phosphates and dissolved nutrients. During the cycle period and before our first water change, the water probably contains elevated amounts of both organic dieoff and overlighting the tank may predispose to algae blooms. By limiting early growth of the bad, we give the good time to catch up and balance the system. SH
 
There is a method of curing liverock called phyto cured rock which works along the lines you have mentioned.

Phytoplankton is added to curing rock and under bright lights they multiply and comsume all the nutrients in the tank over a short space a time, this allows a greater number of organisms to survive the curing process.
 
This Phyto intreuges me.

SH. phosphates and DOC's are absorbed in the algea growing process, but what I was thinking of is doing something to reduce all of them and allow the desirables to live, algea blooms happen but the thing about undesirable algeas is that they dont stay around forever.
 
I dont cure my live rock, although i might if i had super-delicate corals or nems. I think curing it for weeks is a waste of time and space. :/
 
Do you maybe get cured live rock from your lfs? Because if you buy rock that hasnt touched water in two days then you are left with a metric ****-load of nasty decay. Even the toughest fish die off in a tank in the early stages of traditional curing.
 
It probably is. It's in their display tank so you can bet your balls it's cured. :lol: or their idiots if they put uncured LR in their display tank.




P.S.-can't you put in uncured LR in your tank when your starting out?
 
One of the reqasons why a "no light" part is added tothe cycle is to help give organisms with low light tollerance a foothold as these are primarily filter feeders and love high nutrient water. so ponges and sea squirts etc are usually the first to populate in the darkest areas and thes e help suppor the system in reducing pollutants.

Its not the only reasons for no lights but it does help these creatures.
