Ice Cavern
To get into the water temple you will need iron boots and the zora tunic. go into the zoras fountain and cross the icebergs to the left to enter the ice cavern.
in here have din's fire ready. slice the spikes open you will see 5 freezards or more. i had a bad time with freezards i didn't relized you can use din's fire and it will drain your magic i though mp 6 was the only amount you could use it 6 times but I was wrong.
I sliced them up with my sword anyway, once there all dead the door opens go through collect all of the silver rupees to open the next room in this room kill all the ice bats you will kill freezard one at a time. then bottle up all you can of blue fire i had four bottles going.then defrost the chest get the map refill if you need to go back to the rotating blade room then defrost the red ice to find a way to the compass go in it there will be a blue fire torch and some bats, kill the bats then defrost the chest for the compass you will find a piece of heart frozen in red ice on the left side. refill on blue fire then go back to the rotating blade room defrost the other red ice then go pass there will be a freezard and some spikes avoid kill doesn't matter. then you find your self in a room with one moveable platform collecting silver rupees.move the ice platform every where till you get all you need there is one sivler rupee in red ice on the right side refill on blue fire. move that platform to the left defrost the passage way.
slice up any freeard in your way. defrost the red ice blocking your path. open the door to fight a white wolfos (why can't they just call it a wolf?) kill the wolf get the iron boots from the chest then learn the sernade of water from sheik. then srap on the iron boots head down the water open the door go up jump down take right back into the zora's fountain do not leave with out two bottles of blue fire defrost the king zora to get the zora tunic.
