Better late than never, right! Here's a current video of a system I set up in 1997. Initially it was in a 110 gallon, moved to a 200 in 2000, moved to a new location in 2007 and moved to a 240 gallon in 2009. Animals that are from the first year it was set up include a green brittle star (estimated age is 25 - 30 years old), mushrooms, and orange/green zoas and cabbage coral. Unfortunately in 2016 we lost all of the original fish when a new BTA clone crawled in FRONT of a wavemaker within hours of splitting which ripped it open and killed almost all the fish. The Toadstools are daughter colonies from a wild colony original to the system which died in 2017 when the tank dropped to 68° when there was a heater failure. The Pagoda coral was added in 2000 and probably weighs around 30 + lbs. The other notable coral is the Sinualria foliata (Ofwegen 2008), one of the green fingers from Palau. The original frag was bought in 1997 and a colony from that frag was added in 2003 to this system. ( In 2011 I sent a sample to Micheal P. Janes, one of the foremost authorities on soft corals, who identified it as Sinularia foliata.) "Filtration" is just a cryptic sump, no reactors, filter socks, etc. Use of GAC, GFO and HCO3 (bicarb) is sporadic. New sand is added occasionally sometimes some old sand is removed at teh same time.
