Hole-in-head successfully treated

[Navy]

My LH was suffering from HiH disease. It went from a small lesion to a hole the size of 5c coin in just a few days. It was covered with white pus. Pus particles were seen floating around in the water. Quite gross. I was so desperate that I netted the LH out & did a cleansing of the hole.
After washing the wound, I sprinkled yellow powder & some aquarium salt on it. I think it must have really stung!!! It was wriggling abt. Desperate time calls for desperate measures
After a min or so, I put the LH back into the tank & kept my funger crossed. Poor fella must have been so tramatised, it hid in a corner. I switched off the lights & added a heater. Observed it the next few days. To my surprised, the pus disappeared & the hole healed. Now the big fella is back to normal eating & swimming happily. The hole is still there but slowly getting smaller.

Sharing this experience with hobbyist here, hopefully can be useful to anyone who may face the same problem.
