Ok so I’m at the point of setting this new 40g breeder. I had some rock that was setting outside for a year I washed it down soaked it in vinegar a few days and then switched it to bleach which I will never do bleach again but that’s another story. After letting it soak a few days in the bleach and letting it air dry I’m about ready to put it in the tank. My question is I have read people saying soak it in fresh water after bleach but if I’m starting the tank up with no sand just rock and my sump should I still let the rock sit in fresh water for a while?
