The purify chamber doesn't exist in colosseum unless your mistaken for xd.
you use the purify chamber by putting Pokemon in it and when the choas (or purple thing goes down) it will purifie your Pokemon
u have to max out all the tempos in the purify chamber
You can't because time flutes are used to purify Pokemon in colosseum.
well you have to put the shadow pokwmon in and then put other Pokemon in. which Pokemon you put in depends on how fast it will purify.
The same way you would any other type of Pokemon. If you are playing Pokemon XD, have it facing another ghost type in the Purification Chamber. If you are playing Colosseum or haven't unlocked/don't use the Purification Chamber, just keep battling with it and purify it the normal way. Of course, if this question isn't trivial, and you're just wondering why a malicious type of Pokemon such as the ghost type can be purified, then I'm not sure.
have all 9 boxes in the purify chamber full tempo! In the purify chamber, make all 9 boxes' tempo full (Have different species 'Super Effective') And there you go!
Purify all Shadow Pokemon. Then defeat all 100 trainers in Mt. Battle.
Well, assuming you are talking about Pokemon Colosseum or Pokemon XD: Gale Of Darkness, you need to battle with your Pokemon until its Shadow Gauge reaches zero. Then take it to either the Relic Stone in Agate Village (or the Purify Chamber if you're playing XD) to purify it. If you're playing any other game, the only way to become better friends with your Pokemon is to battle with them.
you have to catch and purify every shadow Pokemon in the game and then ho oh will join your team
You can't level up a Pokemon while it is a shadow Pokemon, but once you purify it, it will regain all the exp. points it would have received when it was a shadow Pokemon.
Put them in the purify chamber with a perfect tempo set.
it evolves at level 30 but its already at that level when you catch so purify it and it will evolve
