Hi, so I am starting a second tank, and in this one it's going to be a fowlr (liked the frogfish too much, got a 75 gallon for one). My previous live rock was cured by a friend who was helping me with plumbing and setting up my system, he's in Iraq now, so I need some more help.\n My understanding is I set the tank up, and let it run with freshwater to check for leaks, then I mix salt for it, let it run a day or two, siphon off till about a third left. Now, I have been getting mixed responses, cure the live rock in the tank? or a secondary container? I get both responses, but no explanation as to why either way. Also, do I put livesand in now? or wait till rock is cured and fill in, if that's the case, how do you get it into the nooks and crannies under the build up of rocks? also, when I "stack up" my rock, are there anythings I need to do to avoid dead spots of water movement? Thanks in advance for your help.
