Well since I last posted the tank has had a few events. First, the breaker flipped when I was out of town for the weekend and the whole system shut down. I hadn't yet added a UPS for backup for the return pump like I planned and the system went cold for about 24 hrs. I was fortunate, only lost a few fish, Pyramid Butterfly, Sargassum Trigger, and one Dispar Anthia, amazing. I just this week received a new fish shipment from Blue Zoo and what nice specimens! About 100 nassarius and nerite snails, a pair of Mandarin Gobies, Sargassum Trigger, Regal Angel, Dot-Dash Butterfly and a Sea Hare. I think they may be my new source for online fish purchases. All are looking good and eating well. The power failure was caused by a Coralavue Ballast. I have already replace it with a Lumatek 250w ballast and it is a quality item and reasonably priced.
