How much water is too much?

Hey everyone i know you should be drinking a ton of water when you are working out/doing cardio, especially if you are on creatine.  I am just curious as to how much is dangerous.  I think I recall seeing that you should be drinking 1-1.5oz of water per pound or something like that, but I can't remember exactly.  I have been drinking upwards of 200oz of water a day and just wanna make sure I don't overdo it.  I am cutting but on creatine to help maintain muscle mass and I weigh about 230.  Can anyone tell me how much is too much water for me?
