im a new salt hobbyist name, is daniel. hello. when i first got my lr i did alot of research on it. i have been told by several hobbyist that most of the living bacteria etc, are on the inside of the rock, and when recieving your lr you should scrub it vigerously and rinse in water saved from a water change, or ro water not tap water. then after scubing really hard, pieces may break off, that you should rinse well and then use small toothbrush to get in hard areas, rinse agian then use screw driver or something to remove unwanted shells or old growth if will not come off with a scrub, rinse agian and place in q/t for 2wks. ihave have done this 3 times and my lr has cured pretty quickly because of less die off. like i said i am new at this hobby and have heard many differant ways of doing this-shoot you are probibly already past this stage!! what does everyone think, am i doing it all wrong? your tanks coming along nicely though
