thoroughly with fresh water, (maybe even leave it lying in the sun for a while) before putting it into the fresh water aquarium ?
understand I may need to put it in a separate fresh water aquarium and monitor ammonia levels for a while. I just wanted to know if 1) it is possible for me to do this safely and put it in the fresh water aquarium; and 2) Will live bacteria eventually grow for freshwater aquarium (similar to the cycle established in a saltwater aquarium?) Thanks >> HI Wallace, Yes, you can use the live rock in the freshwater tank. I would first bleach it, until it turns white. Then rinse it WELL. It will not be dead rock, with lots of calcium, so it will raise your pH in a freshwater tank. This will limit the fish you can keep in your tank, basically to cichlids from Lake Malawi and Tanganyika. Or perhaps cichlids and live bearers from Central America. The rock will, eventually, get covered in algae, but nothing like you see in a marine aquarium.
