let down

[darrin41]

so i went for a weeks vacation out to bc and had a family friend to look after everything , gave him a list of stuff to look after tank , what to look for how to top water off . in the sump and what to use also how to empty skimmer cup and how to adjust and where to keep level at ,,, every day i would ask him how things are , he would reply things are good water level is ok ... so i get home tonight and my frikin tank is dead , whole house stinks like dead fish and things were rotten when i cleaned it out , i saw some of my fish that were decayed... he told me the night before the skimmer cup overflowed and shorted out the power bar ,,, but how do fish go rotten over night ,.,, why didnt he call or get a new power bar i check all equipment and it works . all he would have had to do was plug it all in and if scared of protein skimmer leave it unplugged for a couple days till i get home, so if you see me posting on tanks forsale ,,, im not trying to post on everyones posts im just trying to find a new complete setup ,,, i want a nicer tank and better setup , so if anyone has ideas also it would be greatly appreciated
