Sanitizing?

[emeraldsky]

My friend's betta unfortunately passed today from columnaris and I was wondering the best way to clean the tank and if it was possible to do so withough disrupting the cycle.
He has live plants in there and I'm not sure how to get those clean as well.

Any help would be appreciated, thank you.

There is no way without getting rid of the cycle, you have to take all the water out, and rinse all decorations, gravel, tank walls etc. with a 10% bleach solution which of course will kill all bacteria, therefore stopping your cycle. Let all items soak 20-30 mins in 10% bleach to water solution (1:10) and rinse VERY well with HOT water and allow to air dry until completely dry so the excess bleach will evaporate. Rinse again if you want to be really safe. Re-setup and re-decorate fill the tank and cycle again either fish in or fish out.
