do you have access to a copper test kit in India, or a place that will test for copper for you? are any of your coins made from copper?
I ask because you can put one small copper coin in your filter and as it water passes over it, it releases copper ions into the water, however I wouldn't do this unless I had a way of keeping an eye on the levels of copper in the water. once the coin is in testing the levels should be at least on a weekly basis. oh and you can't have carbon filtration with the coin as the carbon will absorb the copper ions thus defeating the object of having it in there in the first place.
on another note
I have had good sucess treating resistant ich with FMG (formalin aka formeldahyde and malachite green). here in the UK you can buy it premade but I have no idea if the same applies to India.
I have a recipe to make your own but I'd need to know if you can get both chemicals locally.
The copper coin is really no longer used as much as ich will get used to the copper and it will not be as effective. Also its not good to use copper in saltwater tanks, as it will kill all inverts. Also when placing copper in a saltwater tank you will never get all off it out as it will be asbored by the sand/crushed coral or live rock. It will leach backinto the water over time slowly. The best way is has I stated purchase a UV sterilizer if you dont have one already.
