Will live sand cause a cycle?

[sunnyfowlr]

Hello,
My first post...
I am currently working on a 29 gallon FOWLR. I'm basically doing this to down-size (wrong direction, I know!) from a 55gal that crashed during a power blackout a few years ago.
I'm wondering if the 10 lbs of live sand and 20 lbs of dry arag. will cause a cycle on its own. I have about 40-50 lbs of live rock to move into the smaller set-up with a few surviving 'shrooms, hitch-hiker feather dusters (the little red ones with white tubes), and lots of bristle worms. I don't want to move my remaining life into the new tank if the sand is going to cycle.
As yet, I have not seen any Amm. but it is just a few days with sand in.
My motivation for the down-size is to hopefully reduce cost of maintenance and concentrate my PC lighting.

You should be fine as long as you get it all moved and transferred quickly, then give it a few hours to settle, test, and take it from there

Thank you, calbert0

Sorry if I put this in the wrong place to start...

I just added 60lbs two weeks ago and I havent had any problems yet. It got a little cloudy for the fish but after a couple hours, it was back to normal. Just make sure its "live" sand.

Be careful, it could start a new cycle. "Live" sand often contains more dead organic material than live, depending on the sand, you could overwhelm your tank's bacterias ability to process it.
