collecting live sand

[mupwi]

Hi I am planing on colecting some live sand to add to the biodiversity of my tank when I go diving some deep reefs this weekend.
Does bringing live sand up fron depth require a slow acent like with bringing up fish or can I just swim it up at my normal acent rate I dont whant to end up killing all the good bacteria and whatever else makes up the live part of the sand

The sand will need to decompress only if you need to. How deep are you going?

I think the deepest dive will be 28m I have been told that when bringing fish up they shouldent accend faster than 1m/min where as recomended accent rate for divers is 10m/min concidering they live down there and im only down for less than an hour

You should be fine. How far offshore are you going?
What is the temp at that depth?

Have you brought up any before and checked the biodiversity of the sand?
I'm just wondering about the life from that depth in the higher temps of a marine aquarium.

I agree with Cmor. I'm interested in that information as well.
