Will I get a cycle when adding cooked LR?

I am cooking 90lb of Haitian LR for my 90g AGA RR tank.

Will I get a cycle if the rock is fully curred/cooked?

If not will I need to add a shrimp to force one?

If the rock is "cooked" properly there is still life in it. Cooking is just a way to kill bad algae on the surface of the rock but the life inside it should still be there.

I would say yes, you will get a cycle. Cooking and curing are different, cooking may remove some bad algae on the surface but you're also going to cook off alot of the beneficial bacteria as well. May not be a bad cycle, but I'd expect a spike of some sort.

I doubt you will get a cycle as the bacteria in the rock is at the level of available detritus (which is low), transfering it to the permanent display will not add a large amount of detritus, just blast the rock well with a powerhead before putting it in the tank.
Once in the tank if you add your critters too fast then you can create a cycle because the bacteria will need some time to adjust and reproduce so add your bioload (critters) very slowly so the bacteria reproduces to catch up with the new load and you will see no cycle.

Did I write what I wrote? What the heck am I talking about! Well..... Nevermind.
