Maybe I don't understand the difference. Here's a quick history.
7/15 - Initial setup: 75g w/38g sump - Put some mostly dead rock in the tank. (about 30 lbs) It used to be live rock but had been sitting around for a year and a half (long story). The guy who setup the tank for me checked it out, sniffed it, and said we could go ahead and put it in. There were still small bits of purple on it.
7/22 - added 7 Green Chromis - maybe these were the cycle fish? they died off one by one over the next week.
7/24 - Ransacked by brown algae - I've since learned this is the di
atom phase
7/29 - Added 20 snails and 7 hermits.
8/8 - Brown algae mostly gone. Some green algae, hair algae, round white puffy algae
8/15 - Hair and puffy white algae gone.
8/19 - Added about 40 lbs nice live rock...few more snails and hermits.
8/21 - Added 3 emerald crabs.
Was told to wait at least a week before adding any fish after putting the new live rock in. Recommended fish were Green Chromis, Blue Reef Chromis, or Talbots Damsel. So was hoping to add some this weekend.
What are your thoughts? Thanks again!
