To cycle or not to cycle....?

Hey guys,

I just recently had a tank made. A custom 2.5g. My question is this:

If I take 2.5 gallons out of my existing tank, only used cured live rock, but purchase 3 lbs of live sand, will the "new" live sand cause a cycle? Or will the existing water, and cured rock negate a cycle?

Thanks in advance!

You probably won't have a cycle but give it a week anyway. In the greater scope of things a week is nothing.

if the live rock is from your existing tank also then there won't be much of a cycle

if it is recently purchased live rock then there will be some cycling

in any case I wouldn't waste the money purchasing live sand--just take a cup from the other tank and seed new argonite.

It is similar to moving a tank. There may be a mini cycle that takes a day or two (it that long). But like Agu said, give it a little time to stabalize and get the sand up to speed.

Oh I missed that the new sand was all live. Yeah, just get regular sand and seed it. This will save money and avoid the possibility that the new live sand has a lot of die off which could cause a cycle.

Great guys, thanks to all! After I posted I thought of just seeding some new sand with a cup of the existing sand. I keep forgetting it's only 2 gallons! LOL!


Thanks again!
