replacing sandbed help

[grundig5]

Hi,
I am getting really frustrated with my sandbed, as its primarily Kolorscape sand from HD and it blows around like crazy unless I basically cut my flow in half. I would really like to replace it with some aragonite so I can flow freely! I'm just looking for suggestions on how to proceed without stressing my fish and corals too greatly.

I have a 75G with a 30G sump, about 120lbs of LR, 4 fish, some inverts, mixed reef (only 1 SPS, the rest relatively hardy LPS/zoos). I have a spare 20G tank, a few heaters, some extra powerheads, aquaclear50 filter, etc. Whats the best way to do this?
Also, how much sand should I order to cover my 75G with about 2 inches? I guess its basically 60 or 90 lbs. Thanks for looking!
Josh

I think Kevin just did this and he had his plan on the thread. You defintely need to remove everything. If you do that and keep your LR and corals somewhere with flow and heat it should go fine.
