I am looking to upgrade from a 14g Biocube to a 20-30g tank. I have checked both the Biocube 29g and the Finnex 20g. They both look good with the additional features I can have including better filtration and refugium option.

I am not completely sold on either and was hoping I could get some leads on a good tank.

Also once I get the new tank what is the best way to move my reef from the 14g to the new larger one and how do I add extra live rock and sand? Do I have to get the new one going again using fresh live rock and sand and waiting 4-6 weeks or can I use the 14g water I have from my present reef and add extra water/sand/rock as I need? How do I get my fish/corals and cleaner crew acclimatized to the new tank?

Just add the extra sand and LR, then put your fish in a bucket and transfer as much water from your old tank too the new one, let it go for a few hours then transfer your fish in just remember to acclimate from the bucket too the new tank. Its the temperature that is your enemy.
