need help. Upgrade questions....

[jay2525]

Hey everyone, Im upgrading my 90 gal. mostly sps to a 220 gal. Can I simply add the necessary amount of water to the 220 and transfer the contents of the 90? I don't really want to add any more rock. I want the system to be very open. 90 gal has been up and running 2yrs. just short of 200lbs of live rock. no sand. thanks...

Your bio-load will will dictate your live rock needs.IMO you should have as much of your rock as possible up in the water and off the bottom with lots of flow.

right....I won't be changing the bio load at all. I guess what Im trying to figure out is if there will be any sort of cycle due to the "new"/additional 100 gallons of water. Thanks

You should not have a cycle if your worried about it do water changes and save the water. I used my 220 gallons and around 150 from my fam's tanks and added around 200 new and I did not cycle my tank and that was with all new sand.
