:lolspin: Thanks alot mnestroy, I almost spit pop on my monitor !!! :lolspin:
There are only 3 ways to KILL marine ich. They are hyposalinity, copper, and the transfer method. If you dont want to QT your fish, help them fight it off by feeding them alot and removing any stressors....
Once you dont see the ich on them doesnt mean anything, it is still in your system, just at a different stage or the fish just arent showing....
A UV only kills what passes through it, so you will never get rid of all ich with it, only the parasites that go through the UV. Unfortunately the UV also kills good stuff that goes through it. IMO, UV's are a waste of money.
Heres a REALLY long read, but a good one on marine ich...
