UPGRADE FROM A 20gal to a 30gal.

[justgotwet]

I am upgradeing and want to know if i will start a mini cycle if i use most of the water and live rock from the 20gal. I also want to add 2 more
pieces of dry rock. Should i wait before i add the dry rock?

You should be fine. Stirring up the sand may cause some nitrate and phosphate spike but it shouldn't be too big of a deal.

Anyone else?

Should i put the dry rock in when i move everything in?

Would use fresh water. There's no bacteria or anything in your used water.

Also putting the dry rock in with you live rock is good as the liverock will help seed the dry rock as long as it wasn't previously live and just left to dry out.

Any reason why you wont upgrade to a bigger tank instead.. i upgraded mine from 30g to 65g. Also use your old aand for the bottom and add more sand on top..

I have a 75gal but my 20gal is sitting where the 75 is going to go after i redo the wall so i got a good deal on the 30gal that is sitting out of the way.

If i use freshwater instead of the water from my 20gal would that be the same as starting a new cycle?

What's the rationale for using new water?

This is where freshwater came from.

Beneficial bacteria is not free floating. Therefore you will not find it in the water column. Old water is just that, old and depleted of trace elements beneficial to all tank inhabitants.

If i use freshwater would i have high levels of nirates and nirites?

I always use live rock. Give a quick rinse for any die off.

No. Not if your mixing using RO/DI water. Read up on your salt mix. Most salts contain some nitrates but not enough to harm anything.
When setting up a new tank using live rock/sand your always going to have some die off. This is what causes nitrites/nitrates and ammonia spikes, (A mini cycle)It is not from using freshly mixed salt water. All living organisms need to acclimate
