How to KILL my tank, but not "overdo" it?

[civileng68]

Ok,
I'm taking my 90 gallon bowfront and giving it to a friend. I cant have it anymore. Anyways, its been a reef aquarium. All livestock to an extent has been removed, except for a ton of big fat bristle worms.
I dont want to "deal" with them. my tank still has water and I just want to "end" the tank so I can quickly progress forward. However, I am going to be giving the rock back and dont want to "destroy" its integrity long term. The rocks WILL BE CLEANED and the tank WILL BE CLEANED, but I dont want to "nuke" the thing to where the rocks are useless (we know they're of value).
However, i want to easily rid the tank of anything "icky" thats still in it. Inverts and all were removed, except like I said, for bristle worms. There's a ton of em and I cant remove them all and dont want to deal/trap them.
Any safer ideas than say "bleach"?
My friend will be re-establishing the tank from scratch after he gets it.

Why dont you want them, they are great scavengers and help keep things from rotting so ammonia and nitrates dont build up.

I agree, bristleworms are awesome.
You could probably just do a freshwater dip and get most of them to come out of the rocks and into the water container you dipped them in.

So the question is this, is your friend going to immediately set the tank back up? If so keep the worms. If not why not put some gloves on and just set the rocks out to dry or like mentioned give them a good fresh water dip and the stuff should come flying out of them.

Thanks guys. Yeah if I were keeping the tank, I'd definately keep them. However, the tank is going into dry storeage for a while. Everything in it will be replaced (living things). Rocks will be dry storaged for a while too. I didnt want to get my "hands" on them. They're going out one way or another but I didnt want to have to risk getting bitten by one, or handling it in any way shape or form.

ok, well yuo should still dip them before dry storage, this will get alot of the stuff you don't want to die and stink to come out so when you reuse them someday they will be alot cleaner and ready to use.
