Hey guys. I'm fixing to start a 40 gal reef tank. I have bought nature's ocean live sand and dry rock to start. How long should I let the tank run before I can add fish or coral? Also i have read some other forums on the dry rock. They say to rinse with ro water is it ok the rinse with regular tap water or do I have e to rinse with ro water? What is the difference?
Thanks
Thanks
