Just use the rock and water changes. I have 40 lbs of gulf live rock that i have gotten in the last month or so. I setup a 20 gallon to keep it in with a heater, two koralias, a cheap led light, and two fish so something is being fed and keeping nutrients going. There wasnt a lot of die off, but definitely some. The rock is beautiful. The water had a slight smell for the first few days. I did 50% water changes for the first few days, then 25% for a few more days, now i do a 25% every few days, and the rock is completely usable(probably is anyway after just a few water changes, and a visual inspection/smell test). I have added a few chunks of it to my 3 month old reef which i started with all dry rock. I pulled out some of the dry and replaced it with the gulf rock. Heres my 30 or so lbs of it, minus what i grabbed and put into my reef. This is my first time getting genuine live rock. Its night and day compared to dry rock. Its loaded with purple and red coralline. I was nervous to get real live rock due to pests, but The hitch hikers havent been bad that i have noticed. I caught a few crabs and isolated them, but they may have been harmless anyway. I caught one welk snail, and have nuked a few aiptasias. I read a lot on here first, and agree with the general concensus, the pros far outweigh any cons with liverock
