Re-doing A "sick Tank"

[ProHaloSniper]

Hello,

I am sorry to say that both of my gouramis passed away after a long, hard battle with what I believe was "columnaris."

I currently have a 55gal cycling with no fish in it. This was the tank that both fish were sick and died in. Here's my question:

I certainly want to get new fish, but what is the best way to start this tank over and clear it from all existing bacteria? I was thinking maybe putting small amounts of bleach in the water and letting the tank cycle for a few hours, before taking all the water and rocks out and giving them a thorough bleaching.

Is there a better, smarter, and easier way to kill off any existing bacteria? Let me know!!

Peace.

Overdose on an anti-bacterial for fish?

You'd need to do water changes and add carbon before cycling, though.

Remove everything and clean it well in boiling hot water
everything=dead.
Careful with the tank though!
Hot glass+cold water=dead tank.
If you weren't sure of the illness that killed your fish then don't waste your money on an antibac...
