Welcome, can’t admit to being in the marine hobby that long. Bet you’ve seen some changes in that time
Like you wouldn't believe Colin. Can't wait to see what the next 35 brings, if I'm around that long to see it lol.
With the stress a reef tank can bring??? No chance
Seriously though, it makes you wonder what new advances will be made, total automation perhaps, computers that will nutrients, monitor alk, magnesium and calcium etc and maintain with pinpoint accuracy I suspect isn't that far away, massive reduction in power use. Whatever it will be interesting to see
