had 150gal. reef tanks when I was younger. days of the hot sodium vapor and mercury vapor bulbs and bulky set ups. shut it down in 2008. life changed. divorced,and 25 years later ... saw a reef aquarium on you tube , and that's all I needed to get motivated to set up. WOW! have things changed. I'm so excited about all the modern technology.. now I'm back ! I've set up an innovative marine 15 gal cube AIO. I love it . but of course already dreaming of those 150 gals I used to do... humm time will tell where it leads me.
