Upgrade from 65 gal to 150 gal question

[jp1986]

I'll be upgrading soon from a 65 gal to a Innovative Marine Nuvo 150 gal. The current set up is all HOB filtration, but the new system will have a sump. I planned on transferring all my current live rock to the new tank with also adding some dry rock as what I currently have won't be enough to fill out the 150. My concern is that with the new tank being more than double the size, the live rock I transfer from my current system wont be enough with adding more dead rock to avoid a possible full cycle again. Would I be better to slowly add a piece of dry rock here and there instead of all at once? I will be adding all new sand as well. I do have a Marine Pure block in my 65 gal right now that I will put in the sump of the new system.

I just did this on a bit of a smaller scale. 54 to a 90. I bought “used” live rock from kijiji that had been in other tanks. I didn’t see an entirely new cycle. I also transferred over as much water as I could from the old tank. Not sure if that’s a good idea but it was like doing a 50%water change-at least that’s the way I saw it.
Have fun! It’s really cool having a tank that’s twice as big as the old one!

Some live is better than none. I would get additional live from LFS, any known friends or see if you can locate a local reef club and buy some from members at a good price.
