The video above was taken almost three years ago before a mishap with a failed skimmer pump. I had leaky current going through the tank and got a number of my acros zapped. Thought GFCI and a titanium heater will protect them, but my titanium heater turned out to be not the type that acted as a ground probe.
Although the damage was severe, the majority of the acros survived. They are looking pretty all right now except for a few that I damaged with my light fixture change. Unfortunately I seem to have fried the tips of some of my acros this time. They are recovering slowly.
Wonder if I ever learn...
