Copper may be the least amount of work, but it's the most dangerous method of treating marine ich to fish, and to a lesser extend, to human.
I would suggest you looking up tank transfer method (TTM) for treating marine ich.
Instead of a test kit for ammonia, get some seachem ammonia badge. it's a sticky thing that you stick in the tank under water and it can show you the level of ammonia (approximately) so you don't have to test it constantly.
Another benefit of using TTM is that you can use ammonia binder (like prime) to reduce ammonia to a lesser toxic form. You can not use such binder in water that has copper. It makes copper more toxic.
Good luck.
