50 gal tank circa 2008. Wish I still had some of that Frogspawn. It grew like crazy in a tank I barely did anything to (I sold it on Craig's List for $25 for ~3 heads and thought I was making "Reef Gangster" money).
Water change...nah! 2 part...what's that? Just throw some Kent Turbo Calcium in when you think about it. Testing... OK, but that was an every 2-3 month thing, and I didn't know/care what to do about it. Nitrates hung around 20 ppm, I think. Sump was an unmodified 20 gal Long. 6 x VHOs that cooked the tank all summer.
