I'm taking Dakar's suggestion and posting this question we have been PMing about. As some of you may know I'm planning on setting up a tank next month. I now have a source for established live sand, LR, clean up crew (50+snails, 30+ crab, and a couple of shrimp), a few corals and a couple fish ( a guy is down sizing). I was thinking about setting the tank up 1/2 full of new water, adding the sand, wait a few hours for the big stuff to stop snowing in the tank, adding the rock along with whatever water I can get from his tank. Would it be OK to add the other livestock after the water has mixed and heated back up or should I wait a while? The only concern I have is that it's an hour drive from his place (along with a couple hours to empty the tank), then a few hours to get the sand, rock and old tank water in the tank and up to temp, is that too long for the livestock to be out of the heated tank? Dakar was concerned that there maybe an ammonia spike with the established sand being dumped in the new tank. The sand is only about 9 month old with a descent sized clean up crew so I don't think that there should be too much crap in the sand. What do you guys think about this idea? any input is greatly appreciated.
