I'm new to this.I am planning to start putting water and salt mixture in my 90 gallon aquarium tonight.I plan on getting LR in a few day's.My friend has some LR that I will be buying.My question is,can I put the LR in with out curing It? The LR was in a established tank already will putting the LR in my new aquarium make It become dead again?Any suggestions would be greatly appreciated thanks..
