I Left for 2 week work trip. Came back and tank crashed. Probably been few days, since one of the gfci outlet pop and there was no water movement in main and return pump. 80% death, except for few acan, and CSB. Went out and bought a carbon reactor, and hopefully it lives. But at this point, I think I'm just going to break down most of this and take a long break. About 6K down the drain, never leave everything on 1 outlet.
