Upgrading Tank need lots of help Please

Did you ever use copper treatments in the 75?

Ditch the FW sand and clean tank with white vinegar. Rinse completely.
Get new sand. Wash, wash, and wash again.
Get BASE rock. Rinse and put in.
Fill new tank 90% with new SW.
Get new water to match Salinity and Temp.
Get a rubbermaid storage tub to hold all livestock temporarily.
Fill tub with water from your 29, moving livestock as you can.
Rinse off LIVE rock from 29 in old water and move to new tank
Move inhabitants to new home.



I would recommend waiting a day to move all inhabitants to the new tank. This lets the dust settle per se. Test water params, then move over if everything is OK.

If you use all dead sand, and base rock, your cycle will be minimal. Most likely have a diatom bloom, but that should be it.

 

my total system is 45 gallons
the new system total is 95 gallons
if i put all the water from the old in to the new it want keep it from cycleing?
also im using all RO/DI water will that help?
also i have 60 lbs of live sand in the old tank i cant just move it over?
the reason i dont understand is to me its like a 50% water change only im not taking the water out of the system.
i cant put more rock in there now, i have close to a 100 lbs of diy rock thats on its last two weeks and i can use it.
i dont have to move everything over right now,i can put a pump on the tank to keep the water moving so it can set for a week or month which ever would be best to keep everything a live when its moved to the new tank..

i agree up to here. the new 75 is going to be NEW. once you get it cleaned and filled up as a SW tank, STOP. Put on some circulation, drop in some of the live sand and some live rock from your existing tank, and let the new 75 gal tank cycle. Once cycle is complete then you can transplant everything from your old tank to your new tank and set up your new sump.

trying to jumpstart the 75 will work, but you'll still get at least a mini or bigger cycle, and stressing everything by transferring the livestock into the cycling tank isn't the best plan.

 

well i put fresh ro/di sw in the tank today and im just going to let it cycle when ever the cycle is complete ill move everything over, that way i know everything will live..
