a lot of good information in this article and thread for you jzenob

if you are moving all the stuff from one to the other and adding new base rock or fully cured live rock and a new sand bed (moving sand beds has proven to create issues for many people) - then what you have in effect is a large water change

Horkn just transfered his stock from a 90 to a 180 home made wooden tank and thats the most recent upgrade I recall on this site- he did not cycle the new tank independantly he just moved the water and rock etc from his established tank. hopefully he will join in with a few tips

no need to moves half the water just acclimate the livestock to the new fresh sw

 

so basically I can lay down my sand bed.....put h2o in the tank....move all my live rock to my 150...hook up everything....then just acclimate my fish and corals and I should be ok.....?

 

Yep, I just moved a 90g contents to a 200g in wall tank I made.

I used all new sand, minus a few cups of LS from my year old 90g.

Use established LR, and I used about 75% of my old water from my 90g. I had zero issues that were not my fault, and even those were trivial at best.
All I lost was a chromis, and aI accidentally fragged an encrusting branching monti. That is all that happened that was bad.


You are using new sand, right? if not, melevs reef apparently has a good way to wash the old LS and use that in your tank. I did not take that risk and used all new stuff. Nothing is alive in it to die and cause issues. The LR was all either from my 90g established for a year, the sump from the same 90g, or a tub that i have been keeping the right temp with a heater, and a powerhead, and doing water changes from my 90g, into that 17g tote.
If you have any questions, PM me, or I will check in here often.

+1 - I just did the same thing going from a 75 to a 150. Did it all in a day and didnt lose anything.

 

I just moved my 72g to a 150g about two weeks ago and here is what i did.

I drained the water from the 72g to rubbermaid tubs and placed the livestock into those bins. I the moved the 72g out of the way and placed the 150g in its spot. i then transfered the sand to the 150g and added some new sand. After that I added 30g of the old tank water to the 150g and placed in my rock structure. After that I filled the rest of the 150g with a combination of old and new water. So in total I probably had 60g of old water and almost 120g of new (adding in the sump volume)

Since doing this I have had a mini cycle that is still going on however no livestock or corals have been lost in this proccess.

 

I just moved a 125 from someones house to mine, and then moved the 125 to a 75 because my wife wanted a smaller one. I used a method similar to above - however i used pretty much all of the water from the "other tank" and then only added new for the top off. Then water changed later as usual...

Also i had a 100% new sand bed. Ive heard that disrupting the biological layers of an old sand bed can create a cycle in the new tank in itself.

Anyway, i have been testing religiously for the last 5 weeks. No cycle whatsoever. Everything has read zero.

I had about 120lbs of LR that i kept completely submerged during the moves. Nothing was ever out of the water for more than a few seconds.

Good luck.

 

i see a lot of these upgrades are from (average) ~90 gallons moving to a ~150 gallons.

After we move, I plan on going from 55gallons to a 180 gallon.

Same thing? No reason the extra large volume increase would change what you guys are saying?

 

I can't see any reason why the larger water volume would change anything.
