How do you get to the water temple on Majoras mask N64?

first go to zora's home then go past the frozen king, as an adult.hop across the ice to the hole. go through the ice maze. Then you'll come across a chest. behind it there should a hole with water in it. if not this is not the right chest. open the chest. you'll get iron boots.then shiek will show up and teach you a song. play the song.you'll transport to on top of the temple.(believe me it doesn't look like it.)put your iron boots on.jump into the water below.get out your hookshot and shoot the diamond above the sealed door. it will come out. the door will open. go into it. you are in the water temple.
