I would say when I first got a reef tank after having fresh water for 5 years in 1998. First tank was a 90 gallon oceanic that my brother still is using today and weighs as much as a 180 gallon of today with thick glass. I was told 1-2lbs of live rock per gallon of water, 20% WC weekly, at that time I was also told 1 watt PC light per gallon with 2 MH 150 supplementing. Back then it was kinda hard to find drilled tanks so standard was HOB skimmers and canister filters. I used two HOB canister filters with a lot of rubble rock in place of a filter. I was able to grow anemones, zoas, some LPS, and even had a couple birdsnest. Everyone always talked about DSB so I had a 6" sandbed that was never touched. I must have been lucky back then as I had a couple large angels that never touched zoas or corals as well as a butterfly a tang and couple clowns. We all wanted coraline purple covered rocks and would pay extra for rocks that were covered (I am guilty of at least a few rocks in that tank). I did add a skimmer after tank was up for like 3 years but didnt notice any difference in growth. Might be why I'm thinking about removing my skimmer on my current tank.

. I wish I had my old photos, unfortunately the ex has all the photos. I used to make my own food. I wish I could get old school live rock and start a new tank. LPS corals ruled, lol.
