LR and new tank cycle no ammonia??? is this true

[untamed]

Yes, that is mostly true...but you have give some thought to adding the fish.

Putting your new LR into a holding tank with water movement, temperature and lighting is essentially just like putting it into an aquarium. You'll get some die off of things which should generate a cycle and create a bacterial population that you need. Once completed, you can transfer this rock into your new tank and you should not experience much of a cycle.

The key is that the bacterial population that you will create will be based on the "load" that your rock experiences while it is in your holding tank. That load doesn't have any fish or food being added. Don't assume that this means that the rock will be able to suddenly absorb the increased load associated with a bunch of fish all at once.

In other words, yes you can avoid a cycle by curing your rock in this way..but you will still need to add fish SLOWLY to build the system's bacterial population to match your fish load. Too many fish, too quickly and you'll still create a cycle that can kill the fish.

so do I still do waterchanges on the LR well it is in the Tub? and once the rock is cured and everything is stable to so Put just the rock into the tank OR do I put the rock and the water in the tank?

Since you've said that you want to light the rock while curing, I'm assuming that you want as much life to stay alive on your rock as possible. I agree with that approach, but others would disagree and mainly just want their LR to house bacteria and not much else.

So..Water changes... Yes, I would do them while curing the rock. You'll reduce the build up of ammonia and nitrite which can both be harmful to anything trying to survive the cycle on your rock.

When you go to transfer the rock to your new aquarium, there is no particular reason to transfer the water also. Doing so would just mean that you'll need to make less new SW to fill up your display. No bacterial benefit either way.

One word "stability"

I never used to believe the reports of this product, until I tried it on a 180gal bowfront.

live forck was semi cured
sande was new in bag
H2o salt and RO water

The tank seemed to completly miss the ammonia spike. Never showed much ammonia when tested throughtout the 2 months.

I am a believer now.

Now to test a smaller tank with un-cured rock.
