I hate to be blunt and I hate that this comes across as rude but fish keeping can be a bit of an expensive hobby. If you can't afford to properly care for your fish, maybe you should look into a different hobby.
In my opinions, there are two things you should spend the money on. Test kit and filtration.
There's another member here that lives in the Phillipines (i'm not quite sure exactly where) His screen name is Lupin and he might be able to help you figure out how/where to get the necessary equipment.
