Seeding A Bunch Of New Rock

[MarkoD]

so i've been in the process of upgrading to a larger tank. scraped the idea of the 150 gallon (sold it) and have finally decided on a 180 gallon tank, 40 gallon sump and 30 gallon refugium with DSB.

tank will be done being built and will be done this weekend.

at the moment, im seeding a bunch of my coral baserock in my 55 gallon





so i was thinking about transferring the live sand from my current 55 gallon into the refugium and filling the display tank with about 2 inches of new aragonite sand.

i've heard bad things about moving sand from one tank to another, any insight?
