so should i leave the fish out of the 29g and let all 4 tanks run together for a couple of days than reaclimate the fish, and put them back into the 29g???
Well, since you are using all LS and cured LR, that sounds like the best course of action to me. If you have a place to keep all the fish (and corals) until you are *sure* all the params are OK, this would be best. Even though the sand you will be adding is live, there may be a mini cycle due to disturbing/moving the SB, but it shouldn't be bad depending on the condition of the sand. Were you planning on changing/adding to your filtration? Skimmer perhaps?

Looks like this will be a really cool project though! Show us more pics ics
