75 gallon.
I hate my rock structure
I'm going to pull all the rock out, disgard a few, add a few, complete restructure. I will be disturbing the DSB more than I'd like to but can't get around that.
I plan on setting up a holding tank to put most of the livestock in. I'll also have a HD trashcan to hold like 20 gallons while I work.
How long can live-rock be exposed to air before it has significant die-off?
Your experiences, advice, cautions... would be appreciated.
