Man,I"m so sorry to hear.. That's a total nightmare.
Are you going to be able to get a tank to replace the one that was ruined? I hope so.
Long story short, I had to throw away a 300 gallon.. Was so painful. I almost got out of the hobby for good.
Luckily, I was able to temporarily house the fish and get a new tank..
So hang in there, I know this is painful.. I hope you stay in the hobby.
