Even tho no one responded here's an update incase some1 has a similar issue:
I've been doing Melafix baths. At first I did the method of dipping a toothpick in the Melafix then moving it in the water and left him in for 20-30 mins, for a week nothing changed. Then I was advised to put it on his eye instead of leaving him, and using a syringe to put 0.025mm (I think) of Melafix in the water. I think it has slightly gotten better.
