Thanks for all the good info.
I acutually have about 100lbs of live rock and about 100lbs of live sand that was in my 105 when it broke.
It is in a 55g with pumps and skimmer right now, waiting for my 215 to show up.

I was just wondering once my new tank gets here and I add the RO/Di water, sand and rocks I have, how long I should wait before adding cleaning crew. I already have some snails and crabs that were in the tank before, but I am not sure how many have survived.

Also, is there any laymans formula that says how many of these cleaners you should add per gallon, assuming I will be running a reef system with live rock.

The tank I have ordered is a RR 215 from Oceanic. I am going to see Dan today about a big sump and Fuge.
I have both now but wanted to upgrade.

The info on different kinds was great reading.
Thanks everyone...

Mike
