New 125

If I am starting a new 125 and I am putting 100+ pound of liverock out of an established tank will it shorten the cycle time on my tank?
Thanks

absolutely. you might still get a mini cycle, due to the die-off of the rock being out of the water, but there wont be much. when i cycle my 1st tank, i used fresh live rock, but "recycled" (used) live sand, and my cycle lasted a week.

May I also suggest that since it is coming out of an established tank, then you could use some of its water. This will definately help establish some of the bacteria.
Anything "old" will shorten the cycle period. Established rock, sand or water. You will get a mini cycle, but better than starting out fresh.

Please correct me if I'm wrong. I just can't see why people put so much into "established" water. The bacterial concentration in water is 1/1000th of what it is in substrate pound/ pound. Please tell me what the big deal is.

I could be wrong, but I don't think the established rock in new water will shorten a cycle. I think you will see the bacteria on the Rock begin to die off & turn white causing a normal cycle.
If you can fill your tank 1/2 with water from established tank & 1/2 with new water, that may save some rock die off.
Don't get in a hurry, let the tank cycle on its own. Toss a shrimp in the tank for a couple days & check conditions and wait till things have zeroed out.

Not to be argumentative but the water from an established tank does little good except to provide animals that you are transfering a more stable environment and less change to overcome. If thats teh goal, go for it! The rock has most of the beneficial bacteria on it. Definitely shortens the cycle by introducing bacteria that normally you would have to grow yourself. Sand is another GREAT addition! Bacteria on the rock won't die if you introduce ammonia to the water with live fish or dead shrimp. The rock turns white because Coraline algae will bleach out when "stressed". Good Luck!

Ditto wat UKCATS said. The water will not do any good to shorten the cycle. Nor will aged but freshly mixed, well airated, temperature adjusted water do ant HARM to the cycle. Either in my opinion will be fine for the "transfer" You MAY get a small spike just from stirring the stuff up as well as exposure to air. But if you pull it from one then replace it right into the other. No spike. You do need to be sure and continue to feed the bacteria though. Adding any kind of fish food, a raw shrimp or even fish will help it to carry on. Dont do much of any rinsing of the rock, dust it off some with a turkey baster if you like, then just pull it and replace it. Sand is the same, you can however, shift the sand slowly to one side. Piling it up a little, so the water runs out and then scoop the sand out and place it in the new tank. This will remove some of the decomposing stuff on it as well as keep the new tank from getting quite so stirred up.
